My brand new GO 620 says it has no internet access even when successfully connected to my iPhone via Bluetooth running the MyDrive app. In MyDrive, I can see traffic, but not in the GO 620, which shows it has no internet connection. In the 620's Settings, it shows that it is trying to connect to the internet, but is not successful. When I connect the 620 to the internet via WiFi, it does show traffic. In the car, I'd rather use Bluetooth with the iPhone running MyDrive. Am I doing something wrong?
