adam87a3 Posted September 17, 2018 Share Posted September 17, 2018 I have the single din factory fitted standard stereo in my 07 A3, which has bose speakers. I'd like to swap the headunit for one with bluetooth & usb connectivity. Was wondering if anybody here that has done a similar upgrade could link me to the parts I'll need please? Thankyou Quote Link to comment Share on other sites More sharing options...
adam87a3 Posted September 18, 2018 Author Share Posted September 18, 2018 Found what I needed eventually, just incase anybody ever stumbles upon the thread - https://www.ebay.co.uk/itm/Audi-A3-2007-Onward-Car-Stereo-Full-BOSE-Fully-Amplified-Active-Speaker-Lead/201103252759?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 Fascia, Keys and Aerial connector are quite easy to find. But the wiring I found above wasn't! Alot of companies will ask if your system is half amplified or not. If you have the BOSE system like me, then you have a fully amplified system and require the above. Quote Link to comment Share on other sites More sharing options...
