Hi
completed installation of nav+ with tmc in A4 3.0l quattro, all is well except one problem ,hooked up vagcom to change some codes(module 17 instruments)to include multi function wheel + nav display in cluster,after recode wheel works perfectly but still cd & radio show in cluster but no nav route in cluster.Any ideas :?

My DIS does not always detect that my RNS-E is sending navi data. Turning the RNS-E off and back on makes the data appear on the DIS. In any case, there is only data displayed from the RNS-E when your route guidance is active or when you set the RNS-E to display the compass in the DIS. Could this be the issue you are seeing?

i just found the same thing..

i was navigating to work this morning with a stopover to drop my wife off.. the navi info was on the DIS until i reached my stopover, then it disappeared.. i tried to restart the route guidance - didnt work.. i tried to turn on the compass - didnt work.. so i turned of the RNS-E and it did the trick..

After some research I found out that Audi never combined the red DIS and the RNS-E. If you get the RNS-E you always get the color DIS. This is even true for recent BNS (DIS only) and late RNS-D (the CD Nav+). It looks like there are certain compatibility issues, but they aren't to bad in my point of view.

intersting..

to provide complete information i have the all Red DIS and it seems to work pretty well..

when using vagcom i cannot access module 37(navigation)could this have anything to do with it also on the plug&play harness supplied with nav unit there were 4 loose wires (GALA,ILL,K-DIAGNOSTIC,12V+)i did not connect 12v+ or k-diagnostic cos i didn,t where to connect will this cause problems

About the color DIS, are you sure the RNS-E was never completely compatible with the red screen? I didn't know they offered color on the A3 model and every picture I have ever seen shows the A3 with the patented red screen. It just sounds as though its another coding issue or perhaps a Nav DVD issue with the converting of EU units to the U.S.

My statement was for the A4 (8E) only. As far as know, there are no color DIS for the A3 (8P and 8L) and the A6 (C5). The issue has been discussed in multiple messages on German forums where people installed the EU unit in their EU A4 B6 using the EU DVD. I don't think it's a real issue, once you know how to fix it it's just a little anoying.

AudiA4B6,
Alright, thanks for the clarification. I am currently buying all the parts to put the RNS-E in my 2001 B5 S4 and this was one of my issues before purchasing the N.A. version (A6 of course). As far as the difference between EU and the NA RNS-E, is there any wiring or circuitry differences? Have you heard of any on your german forums you spoke of previously? I am under the impression that all of the RNS-E units have the same wiring and circuitry and most likely programming. The only difference being the faceplate. The way the vag coding is designed, is to run a certain program (send and recieve signals) based on that code you input. Say for example you had an A4 RNS-E, in the vag coding you input the A6 code, it would then look for the GALA signal (acting like an A6 version) instead of the speed signal over CAN. Please correct me if I am wrong.

The people on the German forum don't know anything about the US units, no help from there I'm afraid. But we had already several very good posting here which help to make a decision.

The wiring is supposed to be the same comparing the EU and the US unit. The faceplates are different between the model specific units and the 4B0 unit is the only one which supports a separate speed signal. Any other unit (8E0, 8H0, 8P0) supports only speed via CAN. There was one posting here saying that the 4B0 can be programmed to look for speed either on CAN or the separate speed wire (and both actually work if the car supports both). There was also one posting here which confirmed that the other units can be programmed to expect speed of the separate wire (which doesn't exist on those models and therefore makes the navi not working to well). One thing has been confirmed several times: you cannot get an 8E0, 8H0 or 8P0 unit to look for speed over the separate wire, these models only accept speed over CAN.

The other differences concern SAT radio (does not work with any EU unit yet), IceLink iPod and Dietz video adapters (not confirmed working with the US unit yet) and the difficulties with some very small streets and the modified US map in the EU unit.

And both the EU and US units have an issue with keeping the time from the instrument cluster and the RNS-E in synch (concerns for example pre-2001/2002 cars like the A4 B5 or early A6 C5). Based on what I read so far, newer (2002+) A6 C5 instruments clusters properly support the RNS-E and may fit in the A4 B5. There is no special S4/RS4 instruments though, you can't keep both.

Good luck...

yes you need connect the K-line to communicate with Vag-Com.. the should be a sticker with the pin-outs of the connector on both the RNS-E and your factory radio.. i believe the K-line on the RNS-E is pin 5 on connector B, but double check that in the schematics section..

i hope i dont confuse matters, but i just wanted to mention that when i 1st hooked up my 8E0 (A4) unit in my A4 it was not getting speed info from the CAN.. i checked the VAG-COM coding and it was coded for an A6 (05xxxxx).. i recoded it for an A4 (03xxxxx) and it started getting speed info from the CAN like it was supposed to..

i did not try to hook up the V-signal, so i cannot say if the 8E0 unit will work with a separate V-signal when coded for an A6, but when coded for an A6 it definitely does not get the speed signal over CAN..

hope that helps..
