I have a 2013 Range Rover Sport that seems to be causing interference with my iPhone's navigation. I have my phone mounded via center windshield arm and whenever I use Google Maps in the car its constantly out of position and unable to accurately track. The arrow will be turned various directions or I'll be on wrong roads entirely. When I'm outside of the car everything is fine.

Anyone have an idea what's going on?

 

Have a heated windshield?

 

I think I might… (have only had this car a few months)
