Use the Tomtom Go app from here, no problems at all with Intel based head units.
I have no idea why they develop a new app that does not work with Intel.
There are so many head units with Intel inside.
I don't know any other nav app that has these problems, but yeah, it's Tomtom, they are not the best.
Why using a smartphone in the car if there is an Android unit ?
Too much work before driving.
