Apps I like on my iPhone for RV GPS usage:
Geocaching app - sometimes supplies a fun diversion to get out of the vehicle and stretch the legs for awhile.
Allstays Camp & RV
- see their web page for all the amazing things you can do with this app.
Motion X GPS Drive
- my absolute favourite GPS app/device for driving. It gets it's data live over the cell network while driving around so it's always current. It even supplies live data such as traffic density, locations of construction and accidents, etc. If you're going out of range of cell coverage or out of country and don't want to incur roaming charges, you can preload maps at any time. I've done this in restaurants with free WiFi while eating lunch - it works well.
I've actually considered getting an iPad mini and a dashboard mount to use as a dedicated GPS device in the vehicle as I think it would be a perfect size.
I also use and recommend those exact same apps. I too had a hand held GPS, that I sold on eBay after using the other Motion iOS app - Motion X GPS- for hiking. (Note the app mentioned above it more road specific - thus has Drive in its title) I would rate those two Motion apps as the best cost/benefit ratio of any apps I have ever bought.
As opposed to my Garmin hand held - the Motion X GPS interface is simple and intuitive. If you have cell phone coverage it downloads topo maps as you hike. If you know you are going to be in an area with poor coverage, you can download the topo's before you go out and save them on your phone. It can save your trail route and you can later put them into Google Earth and see the terrain in 3D.
