Ok. I have had my Z1 in less than a week and am still getting to know the ins and outs.
One thing I noticed that has happened twice already is the map screen freezes up when I'm on the highway.
Here's the scenario: No route is set, I simply go to full map view and just keep track of the floating arrow as it tracks me on the road. Both times I have gone on the highway and go over something like 65 miles an hour let's say, the map freezes after a little while. So it looks like I stopped in the middle of the parkway! I then have to go to another screen and then go back to the map view to get it going again.
I tried a soft reset (pressed the reset button), but that didn't help. The VSS wire is hooked up and working fine and I have plenty of GPS satellites in view.
It's not a big deal for me, but obviously I don't want this to happen if I have a route set. I guess I will give it another week or so, since I only installed the unit over the weekend.
But has anyone had this happen to them?
