I use my iPhone to connect to Internet for TomTom life and that works fine - I set my iPhone to Internet sharing and it works very well.
But......... every time I turn of the engine (for a break for example) it does not automatically re-connect the wifi - even if I still have Internet sharing on the phone activated.
To get it working, I have to turn off and then again turn on the Internet sharing on the phone and after a while it works again.
Is this normal procedure for you iPhone owners?
I thought it would re-connect automatically as the Bluetooth does
