My BMW Navigator VI is possessed

[Grumpy Goat]

Whatever number this is, it's ghosting. I'll call Monday, or maybe after the holidays. Chigee looks really interesting, rumors of a 6" version keep me from pulling the trigger. Among other things.

Sorry to hear, although from what I have heard, the latest Nav VI replacements do seem to have a different screen (can't exactly remember where I read that ...)

The Chigee is the only one with the jog wheel integration in the operation, but is not the only one with the built-in BMW GRP adapter built-in - the significantly cheaper Carpuride also has that (but no jog wheel functionality). If the use of the jog wheel is important (as it is to both you and me) then the Carpuride is the way to go. My Carpuride continues to function very perfectly on the Tiger for which it was primarily purchased. 

So far, the Nav VI is still behaving so I am not at the same decision point as you are.
