X5 E53 2005 screen menu issue

[talljames]

Hi all, my head unit screen keeps cycling through the default blue menu then to the normal nav menu. The process is the screen goes black, then it comes up with another menu layout (like a default one) then that dissappears and the normal screen comes back. If I happen to have nav map showing then it will come back to that. Radio all works fine all the time.

Any ideas? Oh, by the way the bluetooth is not working. Can’t seem to get it to pair with my iphone 15. It is a replaced bluetooth module with a working one. Can’t bring up the pairing message on the screen.

cheers
