I have the Navigon App for my iPhone. Works great on the iPad as well. I like the fact that there is no cost to upgrade the app. Map updates are $15 every other year IIRC. I bought the Magellan Car Kit as it was the only one I found that will hold an iPhone while in its case. It also has a built-in gps receiver to improve satellite reception. I use this setup when I travel on business. It works really well. I've had no issues with accuracy or updating of data. Realize that the Navigon app includes maps for either all of the US or all of North America, depending on the version you buy. You can download as much or as little of the maps as you want or need (by state/province). So, it will work where there is no data service.
If you go the stand alone route, make sure that you buy one with lifetime map updates. Otherwise, the cost to keep the unit up to date may wind up making the purchase of a new unit a better choice.
