Land Rover Here Route Planner / Experiences?

Hello colleagues, I’ve just switched from the latest Audi S7 Sportsback to a Defender X-Dynamic HSE D250. Yes, I know, complete change of direction I’m actually only having a hard time with the Infotainment and Navi. I’ve loaded and connected the Land Rover Remote app for Apple, works really well and I like it better than the Audi MMI app. What I don’t find is the possibility to remotely operate the heater over it. Is that possible? Then I’ve loaded the route planner app, previously created a profile on the HP. I don’t get this profile connected to the vehicle although I enter the correct chassis number, the same as in the remote app and there it works. Can someone help me? Finally a question regarding switching between CarPlay and Navi from Infotainment. Since I have activated CarPlay immediately connects to the CarPlay when starting the car and I no longer come to the LR Navi . What am I doing wrong? Look forward to your help Bayerner 62
