Thanks for your reply; I currently have a Zumo XT (Also the 590LM and 595 LM), and I'm having issues with it. Once I build out a route in basecamp, which some range from 400-600 mile day routes, and load it into my XT or the other Zumo's, the route isn't the same in some parts of the route, which has been an issue for the last couple of years since moving away from my original Zumo 550 with Mapsource. All the new stuff has let me down, which is why I signed up for MRA & myroute-app Gold lifetime. A friend of mine has OsmAnd Plus on his phone and has been using it with Kurviger for years. But, after doing my research, I decided to go with MRA cause you can build routes in a Google map look (which I love). I would love to use all one product I bought with my new 7-inch Carpuride (which OsmAnd + works today) with myroute-app.
I also tried loading the route in myroute-app before connecting to Andriod Auto, but it has trouble even loading the route or a search address to route via the search field in myroute-app ( which I tried on two phones, S24 Note ultra and S20 Ultra Note). I'm hoping the amazing folks at MRA/myroute-app will work this out.
