So here's the deal. I've been struggling to get Bluetooth streaming for a while now.

First I tried to get my cell to pair with my M3's (2006) build in bluetooth. It will connect but the first test I did was to make a call. Audio is crazy shitty. Crackling and popping like a mofo. So I played around with it some, and came to the conclusion that my BT module in the trunk was bad. So it got unplugged. Since the OEM module is more for handsfree calling than BT audio, I left that alone and decided to go another route.

The car has the OEM 30-pin iPod connector in the glovebox, so I ordered a 30pin BT adapter. I did some research and got a fairly good one. See link inline below. It arrived. Plugged it in. Powered on. Paired... but when I push the "mode" button on the head unit to switch to BT audio, it says "No Magazine". Same message as when a phone isn't plugged in.

Did some digging. Assumed it might be a conversion issue because I'm using an iPhone 6 with a 30pin to lightning adapter (works great btw), so I ordered the Scosche adapter. Still nothing.


Did some more digging, and found that the particular model of BT adapter that I got does analog audio passthrough. I'm assuming that the OEM adapter is looking for a digital "handshake" to allow the head unit to switch to iPod mode, so I got another adapter. This one that's supposed to use a digital connection.

Still nothing. With or without the Scosche adapter.

So now I'm at a loss. What's the best option for BT streaming in the e46's? I've heard that the DICE media bridge "was" good, but then it was bought by Pioneer? and then turned to ****. I've also seen the Dynavin units, but that's insane overkill for what I'm trying to accomplish.

So what's the consensus? What are you guys using for BT streaming?_a_

My experience is that there is no single "best" BT solution. Chose the one that suits your needs best. They all have their upsides and downsides...

Look here.

I'm using the Bavsound Soundplicity III.

Ease of installation/setup: 5/5
Music quality: 4/5
Phone quality: 3/5
Features and integration: 4/5
+1. I recently installed the Bavsound Soundplicity III and combination with a BMW USB/Aux socket that I located in the oddment tray area...

Have you considered buying a used OEM module from a newer model that supports A2DP?
Not going to happen, newer modules have the Fiber Optic MOST interface and I am not sure if and when newer modules supported A2DP on BMW.

I use the Soundplicity III in my 325 CI M series and it works great. Once in awhile it has lost connectivity and I have to disconnect the 3pin then reset it.
I installed it myself and considering I had to take my backseat out and the glovebox out. It really was relatively simply. Just make sure to leave the 3 pin disconnected after you plug in the 9 pin and wait til your car recognizes the system. Also don't put your car back together until you have finished the initialization and you know it's working.

Just installed a grom Bluetooth adapter trunk install. Took 5-10 minutes to install. Connects to the 2 factory cd changer connectors. That's it, worked immediately. Phone connects on its own once the ignition is turned on. Best $102 I've spent on this car!

I had a Dice mediabridge and that supported streaming music. It worked pretty well, but I recently switched to just the aux input. I just sold the mediabridge on monday. The only thing I didnt like about it was if I was listening to the radio obviously the phone wouldn't work. According to the link above you may be able to link the phone calls to the oem bluetooth and the music streaming to the aux input adapter. Hope i didnt read that wrong.

quidzel came out with a BMW specific bluetooth module that mounts and integrates via the CD-changer in the trunk, and leaves the aux input available up front. They're working on an improved version that should be out in the next couple months or so, that will offer hands-free profile and an overall improved design. If I don't go with the Dynavin I'll go that route.

Just installed the Mediabridge ambr-1500. It's an easy enough install if you're a little handy. Left side of the trunk, back seat, and glove compartment need to be removed, but those are all simple enough. I also had to remove the head unit, because my car had a bmw ipod module from 2006 (or so) that worked, but didn't charge the device, or show what was playing on the display.

The sound quality through the ipod usb interface is great, and the bluetooth isn't bad, though as stated somewhere else on this forum, the vocals sound a bit muted for some reason (especially lower tone voices. high pitch are fine). I had connection issues when I got it, but I flashed the firmware to the latest and it's fine now. However, now when I turn off the radio, the media continues to play on my phone (android phone, i'll test on my ipod later). All the steering wheel controls work as expected. When playing music you can go forward and back, one song at a time, and in my podcast app, I can jump forward and back by the preset number of seconds. Exactly what I want.

Haven't hooked up the microphone, or tried the aux in yet.

Slightly different topic: Has anyone tried both the mediabridge, and the soundplicity from bavsound? The two devices look exactly the same with the exception of the label on the aluminum panel. Even the included microphone looks the same. And since the soundplicity is two and a half times the price, it would have to have MUCH better sound quality to justify it!

That installation looks fantastic. Is there an adapter to go from the bmw connectors to the standard usb/3.5 mm aux ports on the soundplicity / mediabridge?

I just installed the DICE/Audiovox MediaBridge in my '01 325i with standard Business CD radio and used it on a road trip. Audio quality varies wildly with the quality of the music played, but through my Motorola Droid Mini connected by Bluetooth I actually got quite good sound ... good enough that any loss of quality would not have been detectable over the ambient noise of driving on the freeway. Particularly "Night Castle" by Trans-Siberian Orchestra sounded great (as great as the stock speakers can deliver, anyway) across the audio spectrum, at volumes that my family would never have tolerated. A few points:

1) That annoying chirp others have described happens with scrolling text. It's inaudible with loud music, but really irritating in quiet passages. The only way around it is to disable scrolling text. However I could care less about scrolling text, and in point of fact I prefer having the clock display on my radio, which it does with scrolling disabled. Once I turned it off the chirp was completely gone. Interestingly, this also enables access to the tone/balance/fader controls on the radio, which are impossible to access when the text is scrolling.

2) It does have an irritating habit of occasionally dropping the pairing with my phone and reconnecting ... results in about 15-20 seconds of silence before the music continues. Has never happened on a call, and when playing music sometimes it'll go hours without dropping and other times it'll do it 2 or 3 times in half an hour. I have no idea what causes it or how to stop it.

3) The phone audio and synthesized voice menu feedback are MUCH louder than music played over the same Bluetooth connection. That's slightly irritating, but tolerable. If you use the phone's controls to increase the volume of the music output to the MediaBridge it compensates somewhat, but by the time it's anywhere close to the phone volume, loud vocal passages tend to overdrive something (the Bluetooth circuit, maybe?) resulting in some pretty nasty distortion. I prefer to back it off, eliminate the distortion, and just pull the volume back when the phone rings.

4) The MediaBridge permits call answer/hangup using the Track Change buttons on the steering wheel, NOT the phone or voice command buttons. I wish it integrated those too, but it doesn't. To have a true handsfree experience, it's necessary to enable touchless control on the Droid, but I find that the touchless control works well even while driving (you call it by saying "OK Google now" before your command). Actually, it works when the phone is sitting in the drink holder or on the console; not so much when it's on the holster on my belt. Apparently even though the microphone works well for calls, it's not active for voice command, that pickup is on the phone itself. If Audiovox would engineer a connection to the Voice Command button on the steering wheel, and then activate the mic when that button is pressed, it'd be a MAJOR improvement.

5) The nicest place to mount the microphone is in the microphone chamber in the header next to the sunroof switch. Actually the best way (not an original idea of mine) is to swap the position of the mic grille and the switch, which requires a little whittling of the one hole and a little glue on the back side of the other (I used hot-melt glue). Then I hot-glued the mic to the back of the grille, and ran the wire under the trim across the windshield on the right and down the door post to behind the glove compartment where I installed the MediaBridge. This set-up makes for good performance on calls and complete invisibility.

6) The USB is only good for charging and thumb drives ... there is no app for Android that is compatible with this unit (apparently there is for iPhone and iPod only). So Android devices can only play over Bluetooth or Aux cable, and I have yet to try Aux. And the current it delivers for charging isn't what I'd wish ... it'll charge a device that's off, but it can't hold a charge on a phone or tablet with music and navigation active and the screen on. For that you need a higher-current USB charger. Improving the current delivered over USB would be another wished-for enhancement, but again, no deal killer.

So all-in-all I think the MediaBridge is a really good solution and I'm quite satisfied with it. While it definitely could be improved, it beats anything else on the market for the price.

Aux to the glovebox, then run 5v to the glovebox (run 12 from the fuse, then connect a converter from 12v to 5v with a UBS mini jack end. Make sure the power is switched.

Use this converter - it is DC DC isolated and will eliminate ground loop interference:
https://www.amazon.com/Yeeco-Converter-Step-down-Transformer-Stabilizer/dp/B00N0UNJEQ/ref=pd_sbs_23_1?_encoding=UTF8&pd_rd_i=B00N0UNJEQ&pd_rd_r=62HAK8JXVR87Z4E89F2Q&pd_rd_w=kwm19&pd_rd_wg=YrfRB&refRID=62HAK8JXVR87Z4E89F2Q&th=1

Then buy a Miccus mini-jack and connect it to the aux and the USB power. Pair it once.

It is the only adaptor I know that turns on and off with usb power and auto-pairs. As a result, you turn the car on, it turns on, and it pairs. Car off, it's off. Most other solutions are more involved, or require you to manually pair when you get in the car.
