Question: Will this work with MotionX HD app off road?
Document: Took me a few hours to get it working right (to figure out the sequence) but once you have it going, it's very accurate.Apps I've used so far are MotionX GPS Drive, MotionX GPS HD, Waze,  and Google Maps. All work great and no issues. Local services work as well.
Just received the XGPS150A about 21 hours after I ordered it. Can't beat Amazon Prime shipping!I was concerned, as others were that this unit would operate with my WiFi only iPad and MotionX-GPS HD. I emailed MotionX and received a positive answer in less than an hour. Using my new iPad (3) the following apps work fine, Maps, MotionX-GPS HD, Google Earth, ArcGis, iGIS and EasyTrails GPS.
I had hoped to use MotionX GPS HD, mainly because it is so much less expensive than TomTom, which is a very expensive application at around $50. Before buying the TomTom application and then finding out that I had wasted my money, I attempted to get confirmation from TomTom that there were no issues similar to the situation with MotionX.
In particular, I discovered that this is what MotionX, the supplier of several navigation applications, does. If your device does not have an internal GPS receiver, you cannot buy MotionX GPS applications directly from the device (via the app store application), and if you go the iTunes route, you can buy the app but then during the app synching phase, iTunes will give you a message saying that the app could not be downloaded into the device because the application is not compatible with that device.
The XGPS150A, works well with my tablet, for GPS with aviation navigation, and can double for on and off road.
Also, you can preload maps with GPS Drive, but you need WiFi if you need to recalculate your course.I downloaded satellite maps of my area into MotionX-GPS on the iPad, and took a short walk and created a track and three waypoints with the Dual/iPad and my iPhone 4s. One of the waypoints was much closer with the Dual unit and the other two were different, but equally off by about 15 feet. The track was much closer with the Dual than with the iPhone.
Works for all my gps aviation and road map apps on iPad mini. User friendly and easy to set up.
Very nice product. Does all it says it will do . No complaints from me . It will work on Android with an added app and iOS has an app , free app that is making setup easy .
I paired this with a nexus 7 tablet via bluetooth. Had to download an app to make the two work together, but works great. The built in gps was breaking lock while flying. This corrected the problem 100%.
What I have found to work is shutting down the GPS unit and rebooting it and sometimes shuting down the GPS and IPOD and rebooting both (I have had to do this a couple of times in the middle of a round). By doing this, I can eventually get 4 bars on the Map-my-fitness app.
Answer: Yes, it works. I use this on my wifi-only ipad for off-road use and it works fantastic.
