I have the Tomtom GPS as part of the U-Connect radio. The problem is some days when you try to use it, it works fine and other days it comes on, but no map. A few times it has worked fine, but if you stop for gas or something and go to take off again, it won't re-start, no map. A few times it has displayed a message "contact your dealer". So I have been trying it just about every time I use the van and about one out of ten times it does not work. Anybody else having the same problem? This looks like one of those things that when you do bring it to a dealer, it will work fine. But on the way home it will quit.
