I just installed a 9W7 bluetooth module in my 2010 TDi cup edition. My main reason for this swap was to add streaming music over Bluetooth. Well the streaming part works fine, but it's only coming out of the ride side speakers. I read the very detailed FAQ section about this swap and it mentions to fix this issue you need to add a wire from the module to the radio. Can anyone elaborate on this a little more? I have access to all the pins and wires to add the wire but if anyone has pin out information or exactly what wire needs to be added where? Well thanks for any help anyone can offer to help resolve this issue.

I believe Malooscheck makes a few custom wiring harnesses and this is one of them. Here is a direct link, I don't know if it's still for sale or if he still makes them, please post a follow up if you find out: http://vagpartsforsale.blogspot.com/2010/08/for-sale-second-audio-channel-wiring.html

I will also add these notes to the bluetooth FAQ articles.

If you want to DIY harness, here are all the parts. You need 2 VW repair wires and just cut them in half, solder w/your own extension wire in the middle, and plug them into the existing connector. Connect pin 5 to pin 5 and pin 11 on the radio to pin 4 on the bluetooth.

12 pin connector (6×2 rows) – green- 3B7 035 447 B (3B7035447B) – telephone end

Repair Wire 0.5mm – 000 979 009 (000979009)
pin 5 – telephone audio input signal left negative
pin 11 – Telephone audio input signal left, positive

54 pin connector (18×3 rows) – blue- 4E0 972 144 (4E0972144)

Repair Wire 0.5mm – 000 979 010E (000979010E)

I did it successfully last night on my 2010 Jetta, and have some lessons learned I would like to share. I present the original and my idiot's translation (denoted in blue to benefit my fellow idiots):

To reach the back of the radio, I followed the instructions of this Youtube video (they go ultra-slow, but bear with it): http://www.youtube.com/watch?v=SCziyjBEXrQ

To route the wire, I removed the lower trim panel by the passenger footwell. It's about 3 ft long, shaped like a scimitar and is held in by a single T20 screw at the deep end of the footwell. Once you pull this piece out, you will be able to feed the wire up into the radio area without a problem.

Notes:
(1) Got mine from malooscheck. Of the cable he made, one wire was green and the other was white. Do yourself a favor and make the white one mean positive and the green one mean negative.
(2) I didn't take pictures because it was kinda hot and stuffy and I didn't want to break something trying to be fancy.

minor correction/clarification to note:

12 pin connector (6×2 rows) – green- 3B7 035 447 B (3B7035447B) – telephone end

is actually on the radio end (behind the radio)

the 54 PIN connector is on the bluetooth module end.
