GO 6200 keeps switching on and off
My GO 6200 has recently started displaying an odd behaviour. Everytime it is disconnected from external power (either when the car is switched off or when it is unplugged), it switches off (as it used to) then switches back on and off repeatedly, showing only the TomTom logo on black screen before switching off again, until it runs out of battery.
When connected back to external power, it turns on normally with drumroll and reloading of the app and map and then performs normally until the next stop, where it repeats the odd behaviour.
I have already tried:
1. performing hard reset by keepin on/off button pressed until the text OS screen
2. disabling the option to sleep when disconnected from external power
3. performing full reset of the unit from the menu options
all to no avail.
As a workaround, I am currently switching the unit off (long press and "shutdown") before disconnecting from power, but this is extremely inconvenient and I am unable to use it running on battery power at all.
Has anyone ever experienced this bug and been able to overcome it? I appreciate any help in advance with this.
