Marc R Posted November 2, 2012 Report Share Posted November 2, 2012 Hi Guys I have some troubles getting my RNS-E to work properly in my RS4 B5, i was kinda hoping you could help me out here... I know this has been done a lot of times with some slight things that don't work 100% like the "clock issue" but my retrofit doesn't seem to work ok at all. I got the plug and play harness from ebay and bridged the can signals @ the TMC box under the dash,so far so good. Next thing i did was coding the RNS-E expecting it to work ok, but no luck. The RNS-E doesn't start up but I hear it trying to,now when i remove the plug which contains the can signals and I press the on-off swich it start up without asking for a code with a very faint sound from the front left speaker,after it has started up and I reconnect the can signal plug it seems to work ok. If i switch on the lights of the car , the lights of the RNS-E do not light up. Also the RNS-E doesnt react to the ignition on of off... Does anybody recognise these "symptoms" ? I would really like to get it to work properly. TIA for the input. Link to comment Share on other sites More sharing options...
PetrolDave Posted November 8, 2012 Report Share Posted November 8, 2012 Sounds like either the CAN bus isn't connected - or it's connected to the wrong CAN bus, it has to be connected to the Infotainment CAN bus. Link to comment Share on other sites More sharing options...
craigyb Posted November 8, 2012 Report Share Posted November 8, 2012 You need the orange wires on the TMC unit, if you have them the wrong way around HI/LO etc it will not work. so just try swapping them Link to comment Share on other sites More sharing options...
