Hello, I have finally got my concert to MMI 3G High retrofit installed and component protection removed. It took longer than I planned due to the fact I cocked up my home built LVDS cable (main unit to display) and spent weeks troubleshooting before giving up for a bit as I thought my main unit was fubar. The retrofit includes the DAB radio and AMI mounted in my armrest cubby hole. If you already have the B&O option the installation is not too difficult and I was able to build my own harness rather than splash out on an expensive pre-made one. The cost came in at about £1700, but I hope to get around £400 back on selling off the bits I took out. Most parts came from Ebay, Ebay Germany and Stoke Audi. I've attached a text file of the bits I used. If anyone finds any errors, could they please let me know Lee.
