recent A3 install pics
After plowing through this thread months ago and ordering all the parts, I finally got around to installing everything. I took some pics to post, since some of the original links in this thread are expired, and the info is kind of scattered all over. This is a really easy upgrade to do, and it is so nice to finally have a clean aux in.
I have a 2006 A3 with RNS-E, sat radio, cd changer in glovebox, bluetooth.
First you have to upgrade the nav firmware to 0260, by just inserting the latest nav dvd, and it automatically updates. You can literally borrow the disc from someone, do the upgrade, and then go right back to your old disc and it works fine.
Then find someone with a vag com. I went on vagcomlocator.com and found a guy 10 minutes from my house. It is fast and easy, just plug it in, it reads the codes, and ti even tells you what numbers to change for whatever features. In my case, my original code was 0219637 and we changed it to 0219677. You will see other posts on here saying change to 0xxxx5x or 0xxxx6x, etc. That just means the only number you have to change is the second to last number. In my case, the vag com said to change that number to 7 in order to have both sat radio and aux in activated. We changed the code, rebooted the nav (by holding down the am/fm button and setup button for about 5 seconds I think), and then when you go into the CD/SD mode and push the Source List button, the AUX option magically appears. The guy also changed some codes and turned off the seat belt chime, and activated window control from the remote. Nice bonuses.
I ordered these parts, it is everything you need:
1J0-972-977-G (the grey and purple housing)
000-979-009 (this is a single yellow wire, order three total)
8J0-035-475 and 8K0-973-754 (the black aux-in socket and wire housing)
I ordered from primemotorgroup.com, it was about $50 with shipping. I'm sure you can get the parts anywhere.
The three wires come with pins installed on both ends, so they just click into the sockets on each end. You run a wire from hole 21 on the grey to hole 1 on the black. A wire from 6 grey to 2 black. Last wire from 22 grey to 3 black.
You slide the white block into the grey/purple pieces, and you end up with the fully assembled harness.
Pull out the head unit. You need four key/tools for Audi/VW head units. You can get a set off ebay for $5. Insert them into the slots on the face of the head unit, they click into place, and slide the head unit out. There are release buttons on the side to get the tools back out of the head unit. The wires on the back of the head unit are long enough to pull it all the way out and rest it on the shifter.
There is an empty socket in the upper corner of the head unit. Plug the grey connector into it, and the purple piece flips over to lock into place.
Then reach a finger down into the opening under the head unit space, and pop out the blank button next to the ESP button. Then reach into the back head unit space, and run the black connector and yellow wires back out the button opening.
Slide the head unit loosely back into place. Plug the black connector into the aux socket, and then push the aux socket back into the new button opening. On mine it isn't a perfect fit, but it is snug enough that it won't come loose.
Turn on the head unit to make sure everything works (it does), and slide the head unit all the way back, and it clicks/locks into place. Done! The sat radio, cd changer, bluetooth, everything works just like it always did, there is just an extra audio source now.
I ordered a iphone cable that has both a usb and audio out ($4 from monoprice.com) and the sound quality is noticeably better than the headphone jack. The volume level is perfect, and it's one less cable to plug/unplug all the time. I can't believe I went so long without it.
