GPS veteran Magellan announced the SmartGPS system back at CES, touting its social networking integration and "cloud" stuff. The device has just gone on sale in the US for $249, but along with that comes the SmartGPS app. This is a free download that lets your smartphone talk to the GPS unit. If you don't want to buy a $249 GPS unit that duplicates the functionality of your phone, the app includes additional features for a price.
The free version of SmartGPS lets you search for destinations and plan trips. It contains a full US and Canadian map with tons of points of interest.
