Hi, I have a go professional 6250, I have a problem with it. When I put it to sleep mode, or just press the power button for a sec to turn off the screen, after ~1 minute the device reboots, so its not even wake up from sleep, i see the loading bar, the welcome sound, the tomtom picture ... I tried forgetting my saved wifi network, the same. Tried reseting to factory default mode, didnt help. When i turn it off completly it stays shut down btw. Every update is up to date. Is it a software bug, or my device is faulty? Thanks !
