Any way of resetting the unit? I have the same issue. Disconnected HU, battery, removed and reinstalled... nothing.
Does anyone here know what to do at this point?
Have you received any responses to this issue? I have the same issue and registered to do some research here. I'm beginning to think there is either no fix or no one knows what to do about it and are too nice to say "buy a new one"...
