Recently purchased a non bootable 820 not getting past Garmin logo from a popular auction site, I have fixed this issue and it’s running latest firmware and also reports chipset version as being 2.50, it will not find any satellites at all.
Everything else is working, WiFi, Bluetooth etc etc, so as one last throw of the dice it is either a faulty gps chip or corrupted chipset driver
does anyone have a copy of the GCD update file for the chipset 2.50 or higher that I can try and force the update with or can I edit GarminDevice.xml to try and get GE or Webupdater to try and get an update
