Right i know this has been covered before and i have been discussing it with some of you in other threads but i wanted to make sure i am getting this 100% right before i start buying anything. So i am wanting to convert my single DIN concert stereo to a double DIN RNS-E system. Now do i go DIY and buy the bits needed or go for the pay the money and let someone else do the whole thing? If i do it myself what exactly do i need?? i have found the following bits on ebay: Double Din Cage - http://cgi.ebay.co.uk/Original-Audi...e_ET?hash=item562b88dd85&_trksid=p3286.c0.m14 RNS-E Unit - http://cgi.ebay.co.uk/Audi-RNS-E-DV...tems?hash=item3a5259144f&_trksid=p3286.c0.m14 Would there be anything else i need to complete the install other than getting it programmed via VAGCOM? Also is there a link to a guide on how to do the Double Din from Single upgrade with pics etc and then anothe guide for fitting the RNS-E unit? I have also found this company http://www.oemretrofits.co.uk/ who look like they will do the whole thing including the double din upgrade for £630 plus £20 to meet them in London for the install rather than go all the way to Leeds.
