I know theres currently X-road, and Navigon apps out there, probably more. I'm Just curious how many people are waiting for the Tom Tom app to roll out to the app store.
A google search will turn up the issues, which also have been discusses on this forum; I don't have links handy - primarily difficulties synching with GPS satellites. I used a friend's iPhone with NAVIGON and had all kinds of troubles keeping the satellite synched to the point it was useless as a Nav device; my guess is Tom Tom went with the GPS antenna in the cradle to avoid such issues.
I am a bit surprised as google Maps works fine so i am not sure what the issues is; just the same I'm waiting for Tom Tom.
When you can get a tomtom stand alone unit (refurbished) for 50 bucks (after mail in rebate) that includes US and Canada maps...yeah I think 100 bucks is bit too expensive.
