It’s not cheap, but the TomTom accessory kit for the iPhone 3GS is now listed on a re-seller’s website. Hopefully the Navigon and AT&T iPhone Apps haven’t stolen the thunder of the original TomTom announcement. But I guarantee the GPS performance will be a lot faster with an external device. I’m not criticizing the internal GPS on the iPhone. It is a compromise design that allows everything to sit and play well within the same old iPhone footprint. For good GPS reception and quick locks on satellites, that compromise is going to get in the way. Especially for anyone who has used purpose built, standalone model GPS navigators. My fingers are crossed in hopes the TomTom at least matches the low end of the navigator market with its hardware/software combo.
The application is said to take advantage of iPhone OS 3.0’s support for true, turn-by-turn directions. The software will have both nation-specific and international maps from TomTom, will work in either landscape or portrait modes, and give voice directions.
The software will reportedly be available for separate purchase from the App Store, and would rely on the iPhone’s internal GPS receiver. The hardware kit, however, comes with its own, separate GPS. It will be one of the first external accessories to take advantage of iPhone 3.0’s capabilities.
