Same, I'd much rather it relies on my phone's computation power and act as a display to show the map and blast the music in the speakers.

I don't care if the connection is cable, bluetooth wifi etc.

Yeah - I was thinking 'if only they had some simple way that you could upgrade the internal hardware every few years' aka buy a new phone.

Plus you can stick the phone/tomtom on the windscreen. I find that rather than being something in my view that's annoying I end up using it as a heads up display, so I don't have to look down at my speedometer any more as it's right there on the windscreen.
