I have this problem:

-when ignition is off, everything is fine. I can type security code and listen to radio etc.
- when I turn ignition ON navigation screen is going back to code entry, but when I type code again it is going to code screen again ....and again and again... (I have the right code)
- same thing if ignition is OFF but I'm turning lights ON (lights for DIS to be exact)

Now I have had my setup for many months now and so far no problems. (I did have this problem @ first when I installed it)

However today I get in the car and it start to ask me for the code, WTF, It was working fine last night.

I know this is a common problem with the A6 pre 2001 but I have a 2000 S4.

I have not yet tried to reset the hardware to see if it will fix it. I will do that later today. (Radio + Setup @ the same time)

Any way to fix the problem for good?

Thanx

Your ECU lost NAV info for some reason. Did your battery died recently, or you disconeccted battery? I will suggest to do exact same steps like during A6 install. Proceed with SOFT reset, turn it of and leave it for about 20 minutes.

B5 platform and C5 have simmilar issues with recording data to ECU.

Also make sure that the date/time in your cluster is set correctly.
