Backup GO 620 Wi-Fi
Have I misunderstood Wi-Fi functionality, i.e. you do not need PC connections as update is done over the air? I can accept that, but if so how do I backup my 620?
I gave up original TomTom probably;y over 15 years ago because I was instructed by TomTom to do something that rendered device useless. Backup had not been a pre cursor to advice given then so do not want to screw it with updates again before a backup on this device.
