I just bought this device and when I first started it, the screen would auto rotate when the device was turned upside down. I then updated it, and now it will not. This device is useless without this feature as I can only mount it upside down. I want the device to auto rotate. I had a Via 1435 and loved it, and then TT said it is not supporting the maps for this model and I should get this one. Well, this GO 620 is giant step backwards. Yes, it looks pretty, but it doesn't function as well.
