Hi all fans! :)

This is my first post, so bear with me.

I have a BMW e46 330CI Cabrio SMG from 2003

I have some plans to install a new aftermarket radio (Pioneer AppRadio 4 - SPH-DA120)

So therefore i have some questions for you :)

Right now, i have all the original equipment:
- 2 DIN Navigation/radio with Casette tape & with 6 steps CD box back at the trunk
- Harman Kardon stereo with subwoofer
- Steering Wheel Control

1. question:
- which wire harness adapter do i need? There is 3 types:
- 17 pin connector http://www.ebay.com/itm/PC2-05-4-BM...890?pt=LH_DefaultDomain_3&hash=item3a87d1c952
- 40-pin connector http://www.ebay.com/itm/PC2-75-4-BM...683?pt=LH_DefaultDomain_3&hash=item3cd8f05863
- Wire Harness with RCA cables http://www.ebay.com/itm/PC9-405-BMW...063?pt=LH_DefaultDomain_3&hash=item2a1f28677f

2. Question:
- Which Steering Wheel Control adapter do i need? is it like this one: http://www.ebay.co.uk/itm/Bmw-3er-E...148?pt=LH_DefaultDomain_3&hash=item541cc51ddc

3. Question:
- Do i need to rewire some cables, or is it just "plug in play"?
I mean such as i have the HK system, and read something with the RCA Voltage etc.?

- I also read some with cutting the AC vents/duct back at the OEM 2 din HU?

I know i need this for my aftermarked radio:
- double din panel for aftermarket radio
- Antenna adapter for aftermarket radio

Could you guys please help me in this situation, because i really want to install this asap, and also make a usefull guide with pictures to you later :)

I have searched in the forum and find too many "diffrence" solutions/fixes how to install a aftermarket radio.

NOTE: Yes i know a lot of things about stereo/radio's etc., so you don't have to tell me how to connect 12v etc. :)

Thanks all!

Best Regards:
Jacob Lundgaard
