I just purchased a new GX470, which I love. However, the street names on the nav system have started to flicker. I would almost describe it as a twitch. Initially, this only happened rarely but it now happens about 60% of the time. Sometimes, the street names on one side of the screen will flicker and the street names on the other side of the screen won't. The dealer has already replaced the nav system DVD. Has anyone else had this problem or is this just what the nav system does.
I would appreciate any input or suggestions.
Thanks
DTS
