I started to have an issue where I can not get a signal on any satellite regardless of gps method selected. Tried syncing, updating the maps through garmin express, factory resetting, manual install of gps metadata to no avail.
When it finds a signal, it shows that I'm moving a a speed of 50 km/h, approx. 500 km's away from my current location. I tried to record it and the gps location seems to just drawing donuts on the map. GPS chipset is 4.80, firmware is 8.20, this started after an update last week.
I'm at a loss as what to do at this point.
Anyone experience similar issues?
