My Go 620 has suddenly decided not to connect to my home WiFi or the Personal Hotspot on my iPhone XS Max. This has been a very problematic GPS. Usually the Traffic shows Service unavailable IF and when it's connected to my iPhone but that's rare. TomTom Support in the past has NOT been very helpful in getting me back up... and I'm about to leave TomTom after 14 years of buying GPS units. Any one else having problems connecting to their phone (even Bluetooth is problematic) or WiFi on the 620?
