Can't access radio service menu? Read this...
 

I was not able to access the radio service menu for some time, asked question, read documentation, nothing helped, until today. I had tried ANY (ABSOLUTELY) ANY possible way to get into that menu. Holding the SELECT button, holding INFO button, selecting RDS and holding the right knob...nothing.
Yes, the answer is very simple, stupid me! :banghead:
The problem comes when your navi doesn't know what type of radio unit it communicates to. I had some problems with the NavCoder and it couldn't read settings etc., so I could not know what type of radio unit was my navi set to use. I decided to recode it again with my proper radio model (which is C43 BTW) and voilà...Finally I was able to access the radio service menu by selecting INFO then scroll down to RDS press and hold for about 10-15 seconds the right round knob.
I hope this helps to those who have been pulling hairs out on this.

Hi bro, how did you recode your radio with the correct radio model... ? I am having the hardest time trying to figure out how to access the service menu where you can select NOAREA or USA.... I am able to access the other menu which I select settings under menu and hokd the menu button dow for 5 seconds and it shows a different menu...

-On board computer
-Gps
-Telematics
-Video module

You don't recode your radio unit, but your NAVI. You "tell" your NAVI what radio model you have.

how do I do that ... I am very confused ... I am only able to access that other menu through settings/hold down the menu button..

You'll need NavCoder and interface to your BMW. I got mine here.
