Hi Guys, Crying out for help here. I'm doing a retro fit of an RNS-E satnav in an Audi A4 B6 Avant. All the grunt work has been done, all i need now is pointing in the right direction as i need to purchase the right plug and play adapter harness kit. I've looked on ebay and there are loads of options but i really want to be sure. I need the harness and aerial adapter as i already have the GPS Antenna. The radio i took out was a Single Din Concert stereo on a BOSE set up. If you guys have any links or any sellers that you may now in the Midlands area please let me know as i am really looking to complete the install this weekend. Cheers Guys.
