Since the new iPhone 3G has GPS, a big touchscreen, and a speaker, some see it as a real threat to current in-car navigation systems from the likes of Garmin. And by estimation the GPS companies should be worried, although the GPS-enabled Google Maps application shown yesterday didn't include turn-by-turn directions and other features expected out of a proper GPS unit. But as soon as a third-party made a nice navigation system the iPhone 3G might give the other GPS companies a run for their money.
Money that a smart company — say, TomTom — has decided they'll try to keep for themselves. From Reuters:
AMSTERDAM (Reuters) - Dutch navigation device maker TomTom already has a version of its navigation software running on Apple's iPhone and has plans to sell it to consumers, a spokesman said on Monday.
