MRA route differs when exported to BMW connected app

[rcs]

MRA is my go to app for route planning and love the idea of being able to export it to the connected app, not every bike I use has the bmw navigation.
My problem is that when I export a mra route (made with here maps) to the connected app, the route changes, the route will suddenly vear off on a random route, only to rejoin at the next waypoint. The way I overcome this is by adding more waypoints that I must visit.
Is this a here (mra) and Tom Tom ((connected app) map incompatibility problem.
I would like to carry on using here maps as I also use the bmw nav5 .

Use the TomTom map because the connected App and the CRN uses the TomTom map and technology

@rcs : Hey, im Navi CRN schnellste Verbindung zwischen den WP einstellen und Kurvig auf Mittel dann passt das im Format GPX 1.1 sehr gut. Am besten ohne im Navi feste WP zu setzen denn das kann auch nerven wenn zu viel und nicht genau auf dem Weg. Plane ca. Max 49 WP in der MyRoute Planung und nur die wichtigsten Abzweigungen die du unbedingt nehmen möchtest zu kommst du zu deiner Wunschroute …

Ich nutze ab und zu die CRA- App mit dieser Einstellung und dann läuft das sehr gut.

Fahre aber viel lieber mit der MyRoute-App !!

@Hans-van-de-Ven-MR-MRA Thanks for getting back. I thought this could be the solution, will be a bit of a pain having the 2 types of maps but if they are well organised within my library then it should be ok. Its only when I get given a map in GPX format that i will have to save as a tom tom map, otherwise i can just make a map in tom tom and use that.

@Hubert-Thoring Thanks, if i am making the route then this is possible, the problem arises when i get given the route and there are more than the 50 WP's. But then i suppose i can just use my trusty old navigator 5.
