Recommended Posts

Hello people.

I've just purchased a Audi A4 Sat Nav from a member on this forum, its not been delivered yet but when it does I need to know how to make it put directions up on my dash board? where it says the radio station, miles left in the tank.

I have an Audi A4 2.0 FSI Sport and i currently have the 6cd changer/ cassette player in the dash. Hence the upgrade.

Also i dont have the fancy computer that tells me the mpg, av speed etc. Can this be fiddled with and upgraded.

Hope you can help.

Cheers

Jimmy

I am not 100% sure but I think you will need to retro fit DIS. Otherwise you won't be able to go back to the miles left in tank. As it uses the reset button on the stalk to scroll through the different menus. I might be talking rubbish, but I have never heard of anyone fitting RNS-E without DIS.

It is a very cheap upgrade and well worth it. Even after you have coded it you will still have to turn off the RNS-E, then back on again so that the directions etc will show up on the red DIS. This is a known bug with the red DIS it does not happen with the colour version. Audi only fitted the colour DIS with the RNS-E.

Hi Jimmy

I presume you mean the sat nav that was sold by Mook?

I can retrofit DIS for you so you will have trip computer functions etc. I can also do the coding on the dashboard so that you can see the directions on the display in the dashboard, but as no_idea said there is a bug in the red screen that means it will only show the navigation instructions if you turn the nav off and then back on again. There is no upgrade for that, it's just the way it is.

Where are you located?

thanks,

I;m nr manchester airport about 6 miles from. And work in manchester not sure if thats easy for you guys. Your probably located miles away!?

Yes its the one from Mook. Just waiting to make payment, bloody cheque waiting to clear! Then he will send to me then.

How much would the coding be? is it a difficult job or do you think it can be done quickly.

So to cover what i'd get.

Sat nav set up so i get directions on my display, but i have to switch on and off to get them on the screen.

MPG and other info on the dash (how do i select through each option?)

Can i not just have a colour screen fitted instead or is this a high cost?

Cheers

I'm not that far from Manchester, I'm just the other side of Sheffield.

First of all - colour screen has been done to death on the forum and you need to have an entire new instrument cluster and it must be installed by Audi for the immobiliser coding and everything. Very expensive job (£1000+) but believe it or not people have done it.

If I retrofitted DIS (trip computer) to your car then your wiper stalk would be replaced which has buttons on the end and on the botton which allow you to select the different functions of the trip computer and also what is displayed on the screen (trip 1, trip 2, sat nav directions, off).

Hope that helps +++

If I retrofitted DIS (trip computer) to your car

This is why Jimmy is confused...

DIS is not the same as Trip Computer - they are two different things.

EVERY B6/B7 A4 has a DIS - red ones on most models, colour ones either as a cost option or as standard (on e.g an S4). It's the panel between the instruments that display radio info, range left - even if you don't have a trip computer. I had a B6 1.9 TDi SPort that didn't have a trip computer, but it still had a DIS.

You can have the trip computer, with either the red or colour DIS. But Audi only supply the colour DIS along with the trip computer.

You don't need the trip computer to be able to show the navigation instructions on the DIS, many retrofits have been done on B6/B7s without a trip computer and they all show the navigation instructions on the DIS when correctly coded.

Sorry mate, but I disagree on the technicals there. On the options list for the B6/B7 A4 there was DIS - if you didn't select it then you still got a screen in the middle of the dash. However this was not called DIS. The tick-box option which included the trip computer and bulb check was.

But yes there is still a screen and I wasn't saying otherwise - it's just that we were already talking about trip computers etc.

But jimmy has posted on several websites (not just TSN) that he cannot display sat nav instructions on his instrument panel because he doesn't have a trip computer - which just isn't true.

That's where he started this discussion (elsewhere, not here), he's just gone done the trip computer route because he (mistakenly) has been told that he needs the trip computer to display the sat nav instructions.

Right chaps, I havent posted elsewhere to start with so Dave, where have i posted as i'd like to know who wants to be me!

All i know is i have a display panel in my dash, this shows the radio station, miles in the tank and something else. I want this once I have my sat nav fitted to show the next direction like it supposedly does on other cars. For the time being lets wait till I get the sat nav from Mook then i'll get intouch with shark and get hooked up. Prob a few weeks off for the upgrade as sat nav is costing me a fair bit but think its worth it.

Cheers for your help and advice guys,

Jimmy

Would just like to clarify the DIS/Trip computer disagreement as I was slightly confused about this for a while.......you are both right.....

Yes the B7 did have the DIS as a cost option in the brochures etc.....by which it means the additional features of the trip computer

However,

The manual refers to the screen (even without the trip computer function) as the DIS

so,

Yes DIS was both standard and a cost option.......thanks Audi for the confusion.

BTW, am getting RSN-E fitted in a few weeks and thanks for the information about being able to display navigation info on DIS without having the trip computer.

Hi Chaps

Your superb instructions on DIS have got me the Trip computer functions sorted, Thank you! (Just the washer sensor to go now);)

However... I don't get the turn instructions (when route active) on the DIS but I do get MP3/radio info....

Tried to access the RNS-E via the RADIO & NAVITAGTION sections in VAG-COM but neither would talk to the unit, any ideas? is there another controller I need to enable the NAV in first?

Sounds like your K-line is not connected if you cannot talk to the RNS-E in an A4 with VAG COM

What car is this in Bushman? I'm guessing A4?

If you turn the nav off and then back on again (by holding the power button down) then the instructions should appear on the DIS. +++

Hi Shark,

Thank you for your input, have tried that this morning with no joy...

Yes it's A4 B7 with retrofit RNS-E last year and DIS this week...

I'll pull the unit out and cross ref the wiring as per CraigB's suggestion, but I was thinking that if the media info was displayed then the comms to the DIS were good.

Thanks again, I'll have a nose at lunch if time permits.

The CAN-BUS information (media info and directions) and K-line (diagnostics) are seperate and Craig is no doubt correct about the K-line if you can't reach the unit with VAG-COM.

Also, have you recoded your instrument cluster for navigation? Go to Instruments, Adaptation enter channel 062 and check the value in there.

A062,0,CAN-Databus Infotainment (Installation List)

A062,5,CAN-Databus Infotainment (Installation List)

A062,6,+00001 - Radio (Optional)

A062,7,+00002 - Telephone (Optional)

A062,8,+00004 - Navigation (Optional)

A062,9,+00008 - Telematics (Optional)

A062,10,+00016 - Intrument Cluster (Standard - only coded with 2nd Component)

So you should add 4 to whatever the current value is to enable navigation display on the cluster +++

Thanks Again Shark, I didn't check the insturment for nav settings when I couldn't get to the RNS, I just got the DIS up n running. It'll be a week or so until I get get more quality time with the VagCom PC so I'll check the wiring, pick up the ordered washer level bits from the local parts dept and get rid of the spirting whale too incase that is blocking the use of the DIS for nav...

Your help is much appreciated; it really makes a great car better when you can add all the toys with the right help!:D

Hi

I have an 07 A4 2.7 TDI with computer. I have been reading the thread with great interest. I have fitted a RNS E and like a lot of people the DIS doesn’t work (RED). It would appear that it is quite a simple thing to rectify as it only needs recoding. Problem is I am working in France (for my sins) and as you can imagine the problem is communication regarding the recoding. I visited my local Audi garage and explained the problem and the car goes in next week for them to 'have a look to see if the DIS is compatible' My question is are all DIS compatible and they only need recoding so that the NAV info is displayed? If so can anyone supply me with exact instructions so that I can pass them onto the local Audi garage and they can get my DIS working! Also is it true that it may take a day or two to start displaying, I have read this somewhere.

Cheers

Yes ALL DIS are compatible - but the red DIS on the B6/B7 A4 has a SW bug so when you set a route active you have to turn the RNS-E off and back on to make the route instructions appear on the DIS.

What needs chaging is the value in adaptation channel 62 of the instruments - you need a value in there that is the sum of:

1 to enable the radio display

4 to enable the sat nav display

16 because it's needed(!)

So you need the value to be 21, unless you also have the Audi phone kit when it should be 23

See here Audi A4 (8E) Instrument Cluster (8EC/8ED/8HE) - Ross-Tech Wiki

The 24 hours delay before it starts working has been seen by some people - so if the coding is as above and it still doesn't work then wait a day and try again (remember about setting an active route and turing the RNS-E off and on).

One other thing will the MODE button on the steering wheel do anything after this reprograming? If not how do I get it to function?

The MODE button is a bit weird, if you have an Audi phone kit it switches between phone and "whetever else the radio or sat nav is doing", but if you don't have an Audi phone kit it does nothing.

You can't use it to switch the RNS-E between radio and CD and etc. - it doesn't have that function however the SCSM is coded. An opportunity missed by Audi I think...
