XRoads has released a $19 app for the iPhone that can be used to replace your navigation GPS. It looks awesome and Cars.com has a review, that basically gives it good points, except for the fact that its costly ($40 for the whole of the U.S – the map is sold in 2 pieces eastern and western U.S.). Also, it needs almost 1gb of space for each app (which in one way is good – the map data is on the phone and so you wont need a wireless connection all the time).
I can’t wait to get this app onto my iPhone. But I will probably wait for the next release, when all the bugs are ironed out. (I hope that the app can be used in the horizontal orientation in a future version – I have only seen pictures of the app with the iPhone in the vertical orientation).
