Erk!
I turned the TomTom back on in navigation mode this morning, and it had lost all my preferences – including the pairing to the hands free kit.
I’m back to using the Garmin for wardriving until the blutooth gps stuff is a little better sorted – at least I’ve got that option for now, and at least I can use the naviagation at the same time.
It seemed too good to be true when it was as easy as it first appeared.
