Hi, I have a GO Essential 6" which, until about a year ago, regularly received firmware updates. Occasionally the satnav will display the vehicle position incorrectly while driving. The error is usually by only a few meters. For example, if there is a slipway or a road running parallel to the road I am on and I am travelling slowly in traffic, it will wrongly position my vehicle on that road. Also, when on a multi-level road interchange, the map display will sometimes rotate rapidly in all directions. All of this makes navigation totally impractical when this occurs. The only way to correct it is to factory reset the device. My initial thoughts are that this is likely to be a firmware bug, since it can be temporarily corrected with a factory reset. Just wondering if anyone else has experienced this and if it can be fixed? Many thanks.
