My BMW Navigator VI is possessed

[Ray]

I will reserve final judgement after I see how Garmin treats me and my case.

Don't be grumpy, Grumpy..., stay positive. In spite of the ability to see every example of this problem on the internet, the problem is rare.

Garmin will treat you well.

I'm guessing the high number of cases on the Adventure site represents in part the huge numbers of riders, but also the way some of them treat their equipment. The NAV VI is not the bulky ruggedized, mil-spec device like which they treat it. Not to say you abused yours - we know you have a more pampered and cared-for bike than I. Just saying, that one of the theories has to do with moisture or condensation.
