Tom Tom for me, bigger screen and the rest means it beats a phone hands down, it also means my phone is still charged at destination as the screen, volume & GPS have not been running for hours.
Not exactly a problem when the phone’s plugged into the car audio, thus charging, playing music, and giving directions.
Im very impressed with google navigation on my phone
but I think it like to try a dedicated satnav-
Well, with CoPilot running, the phone is effectively identical to a stand-alone satnav, screen-wise, with the added advantage of being able to play the music that’s already installed.
I’ve tried Google Maps, and their directions are no different to CoPilot; Apple Maps give better cross-country directions, but if you need to get a new route, then you’re stuffed if there’s no phone signal or wifi. Which was the case while I was on holiday for a week last year, in South Devon.
CoPilot worked beautifully, though.
