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.

Your best bet is to post this on audisrs! Alot of b5 enthusiasts there!!!

have you used the cangate module?

I have an RNS-e in mine, does the ebay lead you bought support Bose? if not that may cause your sound problem. I have taken my CAN from the Dash pod. Also if you get the Code bouncing issue, you can enter the code with ignition off, turn ignition on then carry out a soft reset. Should be ok after that.

Clock issues are rectified with a Can gate module, you'll need to contact Bjarne in the USA for one of these.
