@Big-Al-1 If you want to switch to an Android ( maybe just for navigation)
Check out the Motorola Website and search for an phone of the edge series, "almost" pure Android on it and less bloatware of Motorola itself.
I´m using a multisim-card in it, always reachable on the bike!
Relatively inexpensive, good qualitiy and thin, which makes them perfect to place in the cradle.
Concerning the BMW App... not to bad, but far not as good as the MRA app.
The MRA app shows all what I have placed during planning, it shows waypoints and shaping points ( BMW just shows one type of points ) no difference.
BMW is limited to 50 waypoints, all above is resulting in a track.
MRA shows gasstations, Poi´s and much more.
I´m using the BMW app just as a backup and providing CRN users with an appropriate GPX file.
The only advantage of the BMW app is the possibility to use the Wonderwheel.
In order to zoom the MRA app in the cradle, I just bought a SilverFox controller "C1" to have the same advantage of the wonderwheel with the MRA app.
