Hi Jochen.

I'm having some serious problems after coding my NAV unit with your "Navcoder": The nav system was originally set up for Europe, 16:9 monitor, upgraded to MkIV DVD and a BM54 radio (I THINK).

Because I wanted the "NAGSCREEN" (US version) to customize for displaying a funny message, I swithed to US using Navcoder ver. 2.2.1
Often I get error messages from Navcoder stating there is some incorrect parameter or something similar...

After playig arround with Navcoder for a while (experimenting with most options, coding the radio to another model etc...) I realize that I've lost som functionality in my NAV system, the TMC is not working correctly and my ASSIST is gone.

I often get the TMC indication in RED now. When pressing "INFO" button to toggle the RDS-TMC i can see it's swithed OFF! Only way to have TMC status "GREEN" is to toggle ignition ON-OFF. Earlier there were ALWAYS a TMC symbol on the screen: GREY when not active, RED when not receiving, and GREEN when up and running. Now the GREY TMC doesn't come on at all.

Using the NAVIGATION menu to activate it I realize that several menu items has disapeared !!! (I used to have "Traffic Info" and "T-info Plus" in the menus. Because if this I can't switch TMC on, or configure it.
Before using the Navcoder software everything worked just fine, but now it don't.
I can't test TMC where I live since there is no TMC broadcasts, but during the vacation this summer in Sweden it worked flawlessly.

Another thing is that my ASSIST function is gone!
It also has disappeared from the main menu on the nav screen... Instead there is an entry "EMERGENCY". From here you can't make an emergency call...

Do you have the HEX codes for activating (coding) these things???
Is there a HEX code for resetting the radio / nav unit to factory config

Do I really have to go to BMW to have the system re-coded?? (Expensive...)

Please help me track down the reason for this and what to do to correct the problem!

The car is an e46 330d Individual -02

Kind regards
