I used to use TomTom Rider long time ago and after that a BMW Navigator IV(=Garmin-ish) for many years. But the BMW Nav's all get the same 'ghosting' problem after a few years and they become unusable.
(Repair costs 150 Euro every time) This is why I started my search for a follow-up solution and I ran into the same things as you are now
I started testing all kinds of models and brands of Smart Displays with MRA, Google Maps, Sygic, Waze, Calimoto, Stegra .io and Kurviger using both Android Auto and Apple Carplay on several Android phones and iPhones.
My opinion: all AA and AC implementations are still premature today (missing functions, etc.) and most nav apps are ok, but I'm the most unhappy with MRA app due to crashes (6-8 times a day, complexity and a very high risk of incorrect settings or operation due to the unintuitive GUI and too many (unclear or fatal) options. (The MRA app should have a “Simple Mode” button to put it into ' Kurviger mode' to make it rock solid usable! ).
Also, most important, with MRA you can NOT ride seamlessly through mountainous areas without an internet connection! (If you turn of data on your phone, MRA will not be able to do what you need..)
If the aviation industry used software like this, all the planes would fall out of the sky!
But hey, this is just my opinion after 3,000 km of testing the MRA app....
The MRA route planner website is very good though, once you get used to it.
After all of this, I’m happiest with Kurviger: simple, stable, everything you need right at your fingertips without having to search for it. The only thing you should always do when riding a turn-by-turn route, in my opinion, is turn off automatic recalculation. Do that, and it works rock-solid like a charm!
And with Kurviger you can ride seamlessly through mountainous areas when the Internet connection fails!
I use Kurviger app with both Android Auto and CarPlay. With CarPlay, the buttons are positioned on the left side of the Smart Screen, while with Android Auto they are at the bottom, which unfortunately wastes valuable screen space. So I prefer Carplay but Android Auto is also fine.
There is no way at all you can get an exact copy of any of the phone app-views on a smart display. The AA/AC layer is simply preventing that. (for all apps)
Options with Wonderwheel support:
1.A Chigee aio 6
1.B Chigee aio 5
2.A Ridernav R7M.
2.B. ...... none
2.C to Z. See Youtube and look for channel 'Smart Riding Gadgets' for all kind of tests (keep in mind that you are only interested in the models with Wonderwheel support)
