When driving on a freeway, the navigation system splits the screen to show a list of upcoming exits. The list shows Distance, Time, Exit Names and Street Names of the next 3 exits. I notice that the Street Names displays intermittently. I live in the Bay Area (Tri Valley) and in my location the Street Names doesn't show at all. But when I drive down to the south like San Jose, the Street Names started to display. Very strange since this doesn't issue happen to my 2006 Sienna. Does the navigation gets the data remotely? Or does it have anything to do with the version of the micro SD card? I reported the issue to the dealer and none of their Tech experts seems to know is causing this behavior. I was also told that I'm not the first one to report this issue.
