Whenever there's fierce competition the consumer usually wins! Whenever there's competition and a price war, the consumer really wins! These Apps have just been updated for iOS 4 compatibility and support multitasking. Both Navigon and TomTom have begun a Summer Price War!

TomTom followed up by lowering the price of their USA & Canada App as well as their USA only App:

FAQ: Yes, all of the Maps are built-in to the App. No, you don't need a data connection while you're using it (except for the weather, parking and Google POI search). No it does't require your data plan (except for the 3 things I just mentioned). No it doesn't require a Car Kit unless you're using an iPod touch, which doesn't have a GPS (the car kit does). No, there are no monthly fees. You buy the App and you're done.
