Eonon will only respond once per day even when I reply within minutes of their email. So they are making it pretty difficult.

The only thing I have not tried is this

As mentioned, I do not want to splice into the factory harness if I do not have to. I feel like there would be a lot more people with my issue and posting about it if that were the case. Plus, that is 5 years old and the harnesses are just a little bit different.

-------------

Based on this thread sounds like maybe something internally may be wrong with my head unit.

 

Measure the voltage on the power up lead to make sure it (eonon) in fact sends 12V with the key on to your HK amplifier. If I recall correctly, power on lead for HK amplifier in original harness is white.

 

I'll take a look.

Eonon said that I need to connect the two amp wires. There is not two amp wires. The one reply per day thing from them is killing me

 

Hi,
I pulled the stock radio tonight to install my unit. Plugged everything in and powered up but no sound... I also read about connect the two blue wires and could only find the one blue wire. (ANT)

After much googling I was on the point of giving up and it was getting dark so I put the old radio back and thought to leave it for another day. Now I look at it it is simple. The loom with all the RCA plugs I never bothered plugging in as I don't need them. However, in that loom is ANOTHER blue ANT wire and they are the two that need plugging into one another. After that sound should work too.

I can only imagine that this is a design fault which was most easily corrected by making the connection externally.

I'll bung it all back in tomorrow. I tested the unit with my iPhone and it appears to be as awesome as I was hoping.

I hope you solve your issue easily now.

Cheers,
Jon

 

Connect the ANT to the red ACC on the oem side its purple and white

This may be very late, but I also experienced the same thing. You have to take the ANT wire coming from the main car harness adaptor connector (Eonon supplied) that is blue and plug it into one of the other connector wiring (blue also) that plugs into the back of the head unit. There is a split blue wire with ANT and the other was AMP out. The split wire I have was with the RCA plugs for the video in. They make it easy since the car harness adaptor was a male and the connector assembly had female plugs.

 

For the record, you are using the the extension harness that Eonon specifies to use if you have navigation AND DSP systems correct? DSP systems are the Harmon Kardon systems.
If you go to the site and click on the unit it tells you that it is not compatible and you have to use the extension harness. Scroll down bout 3/4 of the way and it say for navigation and DSP systems

Following up to see if you ever figured this out - I JUST ordered a 9450B under the assumption it would be totally plug and play for my 2002 w/ H/K system, since I've heard they are in the past?

If so, how do you like the unit? I really would've preferred an AVIN unit since they look stock, but couldn't beat the price here, and since I'm going to be using CarPlay 99.9% of the time, there was no point to not getting a larger screen.

 

This is controversial for some reason, since some believe that things must look stock/OE. Sorry, but my cars are drivers AND show-ers! I really like the 9450B, but the interface is a bit restrictive as it comes from Eonon. I am a Apple guy, that wanted AppleCar play, but am lost on the Android interface. There is some app that allows you to customize the look (I have done 2 seconds of research...) but the main 2 pages of the interface was a bit easier on the 9150 I had before with Android 9. I swear the music also sounded better on the 9150, but not by much. I installed the 9150 and it would do weird things with the back up camera image, so I returned it - Absolute NIGHTMARE to do that. Ordered the 9450B and put it in and if you are good with Android lists, then this will be OK for you. I struggle, but I can get through it.

Sound is good, screen is very shiny, and I still have not driven it at night. Probably will not get dark enough for my taste and I will end up turning the screen off, using my steering wheel buttons - which work flawlessly! The install is not bad, but be prepared to cut some dash away, and put most of the wiring harnesses on, just to get the amp signal. I pulled wires from the harnesses just to clean things up, mainly the RCA cords.
For under $200, this is a pretty neat package with interfaces that work well. After a few minutes of the car being off, the radio will take 20 seconds to reboot, but it will immediately go into the backup mode, so I can wait for the radio for a few seconds... that 10-60 oil needs more time than that anyway to get flowing correctly!

I started with the car not having Navi, so I did not need to run that extra harness. The amp issue is a simple one to get wired up since they put all of it in place in the Eonon systems.

Funny thing - The 9150 unit was wired with the amp hooked up, no messing with crossover on harnesses.

 

Gotcha, so from what I understand you had an extra step for the h/k system (non-nav) to wire up? Or you didn***8217;t? For the 9450B?

And as I understand it the 9450B comes with CarPlay built in, right? No dongle needed?

 

I would like to install a 9 inch Android headunit with Apple CarPlay support into my 2002 330 Coupe with Harman Kardon.
Right now i am still trying to figure out what system would work the best for my car.

From what I have seen so far the Eonon GA9450B is the only 9 inch Android 10 headunit with builtin CarPlay available at the moment, this is what I prefer.
Besides that there is a Xtrons 9 inch Android 9 headunit without builtin CarPlay, but is expandable with a CarPlay adapter.

I have looked at many video’s and websites to gather information about these headunits.
What i can concude based on what I came across so far:

- Both headunits require the dashboard to be trimmed unless you had another navigation system in the car.
- Steering wheel controls should work with CAN bus on both headunits

Now the most confusing and important part, sound:
- Eonon says you need an additional extension harness A0587 ($70) For Harman Kardon version. It looks like this needs te be wired all the way from the radio to the trunk.
- Xtrons should not need an additional extension harness for Harman Kardon version.

Can someone who has experience with any of these headunits in combination with the Harman Kardon system please confirm this and sum op what additional cables and adjustments are needed?

Yep- I've got the Harman system and JUST installed the 9450B - it works plug and play with the included cords, you DO NOT need the extension.

The extension's only needed if you have factory NAV.

I did have to join 2 of the eonon connectors to trigger the amp, but they're labeled & are spade connectors, No soldering or anything required. One on the main harness, and one that comes off the white connector.

I was weary of the dash trim, but you don't need to do as much as you'd think, and it's 100 percent totally ok to go back to OEM.

You're correct in that steering wheel buttons work on both fine. It's all CAN bus.
Built in CarPlay works fine - just make sure you plug the CarPlay cable into the CarPlay USB slot - it fits in 2 slots on the back of the unit. I didn't realize I plugged it into the wrong one and thought I broke it, but then just moved the plug over and it was fine

 

This is the exact response I was hoping for.
It gave me the final push to order the Eonon GA9450B since they also have an Easter sale going, less pricey and the backup camera and OBD comes with it.

Could you point out with a picture which 2 connectors you have joined? I think this would be helpful for a lot of others as well.
Im also curious where your CarPlay connector is coming out.

I will try to post a write up about the installation as soon as I have installed it!
Ive also seen your post about CarPlay having some weird noise, I will let you know how this turns out for me.

 

Yup! As soon as I can I'll snap a pic, but in case yours gets delivered, there's a blue wire on the main eonon harness, and a blue wire on the white plug that also has RCA jacks on it. Connect the spade connectors and you're set!

The CarPlay one is labeled, just follow the labels- it goes in the space on the right if you're looking down at the unit (I swear this will all make sense haha)

I ended up getting mine exchanged, so new unit should be here Monday. Turned out to be a dud I believe.

Ah! Would***8217;ve told you to get it from their eBay store(s). You can do ***8220;make best offer***8221; and get it even cheaper. I did a bunch and eventually got then down to 225 or so

 

I am still trying to resolve radio reception issues with a GA9350B with HK and without NAV. Did you need to anything regarding the antenna connection to get decent reception? I reset the country setting but still having issues. I am wondering if I have a faulty adapter cable.

 

Guys,
When installing the 9450B in a car with HK and factory nav, is the original BM54 radio used for anything? I think I have a bad channel in that module. I won't bother to replace it if it won't be used once I get a 9450 in there. If it must be used WITH the 9450B, I guess I will have to replace it first.

Thanks,

Todd

 

The business Cd unit? No this totally replaces it.

If you have the Harmon Kardon system though, you may have a bad amp

 

Here are the two wires you***8217;ll need to connect, they***8217;ll read ***8220;AMP-CON***8221; and ***8220;ANT***8221; that should fix the sound

 

 

Beat me to it -

Bringing it back here, just got my replacement unit and the low interference during CarPlay still seems to be there. Anyone else have this?
I may see if I just get a CarPlay dongle and try that, OR go through the hassle to return this & get the 9350B. I really only use it for CarPlay.

The interference is low, but it's there so...

Would love to hear if anyone else hears it! It's ONLY when your iPhone is plugged in.

 

Thanks a lot for the picture!

If you search for CarPlay noise in general there are a lot of complaints to be found with all sorts of headunits. This is an example of someone with the 7" headunit who is experiencing static via CarPlay.
Most issues are fixable via software updates, either iOS or headunit firmware.

A few questions to narrow this issue down:
Can you specify what sort of inteference you experience? Is it a certain noise and is it always there when you are connected via CarPlay or only when you play music?
What phone and iOS version are you running?
Have you tried a different phone and lightning cable?
Do you have your phone paired via Bluetooth at the same time, does unpairing make a difference?
What else do you have hooked up to the radio that could cause interference?

I expect they built in the same thing into the headunit like the external dongle, so i don't think this will solve it.

I should get mine delivered tomorrow, i'll install it as soon as i have it and will let you know what my experience is.

 

Interesting - Very excited to hear what your experience is.

It happens pretty much the second I plug my phone in. I'm using an iPhone 11, with an OEM apple cable - and I've tried a few.

Once plugging in, there's a bit of static, followed by high-pitched "interference" type noise. The noise comes and goes, oddly enough. It's not dependent on an app being open, music playing or anything. It's persistent, and occurs even if I'm in a different app in the head unit. Sometimes it goes away for a bit, and then comes back. Volume level doesn't affect it either at all. As soon as I unplug my phone, it goes away. My phone isn't paired to the unit's bluetooth or anything.

I've tried turning the wifi on/off, no change on either end - tried re-positioning cabled, etc. My guess is it's some sort of processor interference.

I've ordered a 3rd party dongle to see if that changes, with the thinking that maybe it'll distance itself - worst case I can return it. I got the Eonon unit at such a fair price that I'm OK accepting if I need to add the dongle.

Video showing my issue below - turn the volume WAY up though. Like I said, it's low, but it's annoying and it's there. Other than this, I'm happy with my unit. I just need to figure out how to customize the interface, which seems pretty locked down.

Yeah that's a ground loop. It's happening because of the way the head unit is handling the grounding of everything - it might not be grounding the dongle cable properly. I'd start by seeing if there's a continuous ground between the carplay dongle and the chassis. Connect a usb cable to the carplay adatper, and test for ground between the other end of that usb cable and the chassis - there should be 0ohms resistance between them. If that's grounded as it should be, then you'll have to keep looking. Welcome to the rabbit hole...

 

Huh. Opening this thing up isn't quite what I wanted to do, as it'll definitely void the warranty. I've tried moving cables around, shaking things, and can't seem to find where that ground would be except inside.

On these units, the CarPlay adapter is INTERNAL (the new 9450B). So what comes out of the head unit is just a female USB to plug a lightning cable into. There's a specific cable designated for CarPlay, so I wonder if the other USB port will be better, with an external dongle.

Edit: I wonder if running another wire from the unit's harness to a ground would help? Although this ONLY happens when usi ng CarPlay from what I can tell. Would rather dig into it's harness than my car's harness.

 

I have installed the Eonon GA9450B into my 2002 E46 330 Coupe with Harman Kardon, without nav today.

Delivery time took 6 days, pretty decent.
The packaging is alright, you get a box with the headunit, 2 bags with cables, some manuals, and a warranty card.

The installation was pretty easy because i made sure what i needed to do before installing. In my case, no additional accessoires, cables or connectors needed.

I plugged in most of the wires except for the external mic before installation. I used the picture in the guide that came with it, all cables are also labeled. What i would not have known without the internet is that you need to plugin the AMP-CON coming from the supplied harness into the ANT (supplied bundle of cables).

I removed the dashboard trims with the included prier tool.
I pulled the radio forward and unplugged the harness and antenna cable.

I removed the AC, had some trouble removing the small black connector that doesn’t have a pushpin. There’s a tiny tab on the side, I pushed this in with a small screwdriver and pushed the connector out with another screwdriver.

I removed the bracket that holds the radio and the AC, you might need to remove the upper vents for this, I did not have to do this.

I then removed the console storage underneath the AC by pushing from behind, relocated the AC without the proper bracket you could buy.

Plugged in the antenna cable into the new headunit and plugged in the harness.
It comes with 2 harnesses, A and B. I plugged the harness that’s in the car from the old unit into the ‘BMW E46/E39 B’ harness. Make sure to switch over the CanBus to the right harness.

I put they key in position 2, the headunit booted up and I tested the sound and Carplay.

After that I trimmed the side pieces of the dashboard with a cutting tool and a knife until the headunit had a tight fitment.

I routed 2 USB cables and the GPS and WiFi antenna through the corner of the AC unit into the glovebox since i have some wiring to do for the backup camera and OBD.

Screwed in 2 screws in the 2 holes at the top to secure the headunit and put the dashtrims back

What I noticed the first time when I used CarPlay is that I couldn’t change the volume. After backing out and reconnecting my phone I was able to change the CarPlay volume, but it happened a second time later tonight.

Now about the static noise when connected to a phone.
As soon as I connected my phone to the CarPlay adapter, I could hear some crackling and static noise. It’s not obnoxiously loud and not noticable when driving or playing music.

I will be testing this further this weekend and will give an update on this.

Conclusion so far:
I love it! It’s a pretty big and bright screen and it responds fairly quick.
There’s an equalizer built in that is actually more useful than I expected it to be.
CarPlay, sound and steering wheel controls work, which are most important for me.
I can live with the boot time, about half a minute.
Overall it really improves the look and functionality of my E46.
I’ve shown the headunit to a few people and they were all like; ‘wow, that’s nice’.

Great write up! Do you by any chance have a image of the top of the unit? I'm looking for the wiring diagram for the main connector (I think it's 20 pin?) that is usually stuck to the via via a silver label.
Thanks

 

Ordered a third party carplay adapter to try out in the normal USB port, to see if that helps to eliminate the ground loop. Gets here Tuesday, so we'll see!

The noise isn't THAT bad. I'm just fairly anal about sounds and noises and squeaks.

 

Adapter hasn***8217;t come in yet, but interesting data point: my brother in law***8217;s iPhone 7+ doesn***8217;t trigger the sound, yet mine and my fiancé***8217;s iPhone 11***8217;s do. Hmm.

Very strange - I assume it was the same cable being used?

 

Still dealing with radio reception issues with my GA9350B in a 2006 326Ci convertible with HK. I did the factory reset and Eonon sent me an MCU update. I still get drifting reception and no AM in the NYC suburbs. Eonon is now telling me to try a signal amplifier but I thought the convertible had one already. Anyone have any ideas or thoughts on is adding another amplifier makes any sense?

 

I swear I had this issue in a BMW a LONG time ago. I only remember that the antenna amplifier was not being turned on by the radio. I don't remember how I solved it. That's a ridiculous suggestion for you to have to install a separate signal amplifier. That setup is supposed to be plug and play. There's no way your car requires a separate signal amp. I assume you checked the antenna connections? The next step would be to locate the signal amp (I believe it was in the C pillar on my BMW MANY years ago) and check for power when you switch on the radio. I believe I had a 330i with the H/K system at the time.

 

I believe the antenna amplifier might be on the underside of the cover that flips up when you retract the convertible top. It's a box about 2 inches square. There's a single wire going into the box and I believe it's powered through the antenna wire itself.

 

Just installed this system today (the GA9450B) and can echo most of the things mentioned here.

** No sound unless you connect the "Ant" wire from the harness to the "Amp" wire from one of the modular connectors. I hadn't had this one even plugged in because I wasn't using any of the connectors on that plug so it took some googling until I was reminded of this. I really with they would include this instruction (not that the instructions are that great in the first place).

It looks absolutely great in the car. It looks a million times more 'subtle but classy' than say the Pioneer unit looks in my Navigator (which screams 'aftermarket'). It looks like it was made for the space.

Everything other than the amp connect wire was super easy, plug and play. I use an ios device and did not need the usb adapter (as I know there's some confusion about this).

I do have the HK system, non-Navigation and did not need the additional harness.

I purchased the Metra 95-9311B kit for the relocation and it worked perfectly fine. Didn't feel overly flimsy to me and looks good in the car. It is a plastic that shows greasy fingerprints so I need to make sure to keep it clean.

I tried to use a dual USB flush mount port with the Metra kit and it required quite a bit of opening up the stock hole in the Metra kit to fit the dual usb kit I used and more than that, the dual USB adapter I used did not work with the unit. It could be a million things (longer cable run than the unit expects, mixed standards, etc.), but it was $10 so I'll just suck it up and try a different unit and hope it fills up the larger hole I had to carve out.

It doesn't appear that you can dual screen CarPlay apps (which I was really looking forward to) but for the price, this is an absolute steal. Not sure what the long-term durability is, but I'm more than impressed at that price point.

I did not install the rear view camera that came with it (ordered one that is integrated into the trunk lip instead of the 'generic camera'). Even though it isn't receiving a signal it still turns off the display and lowers the volume when you go into reverse (and displays a 'no signal' message).

I did not install the mic that comes with the unit and went with a different one from Amazon. have not tested it at this time.

Having installed a million systems when I was much younger, this 'plug and play' set-up was greatly appreciated. I don't mind carving up my old 'workhorse' Navigator but really didn't want to go too far from stock with the look of this unit and it delivers.

You will need to trim the 'ears' of the center section of the car just under the mount holes a little bit and that's the only 'modification' to the car that you will need to make. I used a cylinder bit on a dremmel to be a little more precise than hacking at it with a blade and it was the least desirable part of the process, but it's in a spot you'll never see and doesn't affect any future use so it's whatever.

Did not bother with routing wires for the GPS since I'll use CarPlay for navigation so there really wasn't too much 'wire routing' for me. Look forward to figuring out how to really use the unit but if you're looking at this or more expensive units, if I had it to do it again, I'd buy this one all day long.

Edited to add, if you're looking at buying, check out Ebay as they sell there as well and have 'Best Offer' on their items. I put in an offer that was $30 lower than their listed price and it was accepted immediately.

 

Also, has anybody found out how to move apps on the home screen?

If I'm in the app folder I can touch/hold an app and it will let me drop it on the home screen but says 'home screen is full' and I don't see a way to edit the items on the home screen to make room for things?

 

Just finished my install (well....it's not "finished", but it's working). I want to know this as well.
