02 M5 MKIII NAV
 

I downloaded some garbage ver. update on the NAV.
Cd won't eject.
NAV screen blank.
Stereo turns off after 2 minutes
Would a download then install with V27 take care of it?
From where may I download this version or most appropriate version?

I believe I can remove cd unless you may have procedure.

Thanks, Paul

Remember you need the MKIII to totally shut down the power before you can unhook it with out damage. Also OS Ver.22 is the last one for a MKIII (3-1/63). Any later OS Ver. adds nothing.
