I had last night a sudden battery failure. Tried to start 2-3 times the engine, but with no luck and warnings and relays gone crazy.
So today I replaced the battery with a new one, and problem solved.
But: My Connect Nav (patched with 9.8 v) is unresponsive. No buttons could be triggered and even could not switch the unit off. I tried many times with ingition key and removing power plug, but seem to be stuck (in firmware). Radio is working smooth the same the GPS unit.

I can only control volume from steering wheel buttons.
An suggestions before getting back to bench?:bang:
