Funky Navigation System Problem

[ThrasherFan]

Weird situation occurred where screen started flickering between map and black screen, then the unit started opening and closing very erratically while the flickering continued. The radio would still work on the station tuned and I could adjust volume on both steering controls and knob on nav unit. Turned the X5 off and the unit continued opening and closing. Pulled the two fuses that control the unit (fuses # 73 and 75 in the right rear fuse block) for 5 minutes, put them back in, started up and everything has been okay so far.

I have the MkIII navigation system that I upgraded from V17 to V22 about 2 months ago and had not had any issues after the upgrade.

Anyone experience anything similar or have any ideas. My only thought is that the fuse removal was acting like a reboot to clear some software/electronic confusion or the fuses may not have been completely seated??

Thanks in advance for any ideas or thoughts.
