I quit using those miniature GPS units with the little screen a few years ago. These may be okay for a car but not an RV (motorhome) – at least not my motorhome. I don’t use the car-type GPS in my motorhome because the screen is too small at the distance it has to set on the dash. Plus, I can’t mount one on my dash (easily and conveniently) since my dash is not even close to level and does not have a flat surface close to the driver. So, I went to my iPad for the solution. We use an iPad so we have complete flexibility and a screen much larger than a car-type GPS. The car-type GPS unit is also significantly more expensive when compared to the GPS apps for the iPad. Maps for these apps are updated frequently and free on an ongoing basis. I use two different apps and both were cheap…
MotionX-GPS Drive… We have used this app longer than any other GPS app and for us, there’s good and bad news. Good… It’s great at finding POIs (restaurants, places) especially running around in strange towns or along your route. It has great segment routing, too. The bad news… On ours, we can only put one trip segment in at a time. So, when you get to your first stop, you have to put in the next segment of your trip. Ultimately, we use MotionX to find things locally all the time but rarely do we use it on our trip.
Premium CoPilot… One thing I REALLY like is that it has a “Vehicle” option (choose your vehicle). I chose the RV setting and then set a clearance height. I set mine for 13-feet of clearance. Also, you can put in a trip with (I think) 50 segments (or stops). You download various maps (I downloaded “North America”) and can use these even when not connected online.
We use a GPS every day in our car or motorhome so functionality and accuracy is important to us. We can easily carry the iPad to and from each vehicle. We do NOT use it to make phone calls, listen to music, or play games but just to help us get from Point A to Point B efficiently.
