Hello, I have a u310BT unit in my Mazda Protege5. Periodically, the unit is unable to track the exact location of the car. It will show a map location around the car, but the car will appear to be 'off-map,' i.e. not on any road. When this happens, the unit will not be able to give GPS directions. The problem happens maybe once every five or ten uses of navigation. Is this problem something endemic in the unit, or is it something that happens because of an improper installation? Is there an easy fix? Please help me out.
P.S. I have the latest firmware installed.
