craigyb Posted November 7, 2010 Report Share Posted November 7, 2010 Have you bypassed the TMC module and connected to the can bus, sounds like you haven't. Link to comment Share on other sites More sharing options...

IT_S8 Posted November 7, 2010 Report Share Posted November 7, 2010 Check here for an in depth how do for the RNS-E on the D2. The canbus is really quite important, even thought it seems to work fine at first... RNS-E Retrofit into a D2.... - A8 Parts Forum Link to comment Share on other sites More sharing options...

RNS-E Retrofit into a D2.... - A8 Parts Forum wow thats quite a read! but i,m still a bit miffed! i was in the understanding that on a 2002 model its just plug and play? i have one plug i took out the rns-d that is not pluged in to the rns-e as it would'nt fit, its the one with the purple clip that i thought went to the s8 dis display.. is this where the can is then? sorry for all the questions al Link to comment Share on other sites More sharing options...

Yes, there is a canbus in that spare connector block, but its the wrong type of canbus. The two wires from that spare connector go straight to the TMC module behind the instrument cluster, and the TMC module (its only intended purpose when it was fitted to the D2) is to convert the bespoke Bosch canbus data into standard Audi data. The RNS-E talks the audi canbus natively, so if you connect it to the wrong side of the TMC, it than ends up talking jibberish on the bus and it still doesnt work properly. The only solution is to connect your RNS-E to the other side of the TMC module, which is where the correct canbus is located nearest. Link to comment Share on other sites More sharing options...
althesparky Posted November 8, 2010 Author Report Share Posted November 8, 2010 ok cool i will get that done then, where on the rns-e do the 2 can bus wires go? Link to comment Share on other sites More sharing options...
althesparky Posted November 8, 2010 Author Report Share Posted November 8, 2010 just an update, got the clocks out today and bypassed the tmc module, found the can bus on the unused rns-d cable and hooked it to the rns-e and bingo i now have illumination and it turns off when i remove the key, it even tells me the track number etc on the dis display, just got a couple of questions for ya..when i hook vag-com up and go to radio or nav it still tells me there is no connection? i,m not sure if i need to change anything within the radio as everything seems to be ok i was curios more than anything as it must now be comminicating via the can connection.... also can anybody recomend a decent way of interfacing a dvd etc with it that also gives me the tv on the move feature.... a big thanks to it_s8 aswell Link to comment Share on other sites More sharing options...
