hi all, I have been battling on with this conversion for a while. I’ve had my entire console out, I’ve sawn it up and modified all other necessary trim pieces, replaced the single din cage with a double din, bought the head unit, modified my loom to provide power to the “Safe Pin” and also had my car reprogrammed by someone to accept my stereo. I bought an RNS-D which came with a CD changer (but no loom to go between the two) so I was going to just install the unit and use it as a 1 Disk unit. First question is, I assume that the RNSD can’t be used without the changer? The CD slot is empty yet won’t take a normal CD and asked for 6 CDs. Assume this is just for a nav disc? My main issue though is the wiring. The buttons backlights will not work. And the RNSD unit will not turn on/off with the car. And also every time it turns on, it wants it’s code input into it. Does anyone have any fixes for these issues? The dash removal/cage refit is all stuff I managed fine but wiring is not my area at all. Here are the photos of the sockets on each head unit: Old Audi Concert: New RNS-D unit: Any help with the above would be grately appreciated. Thanks, Kevin.
