[Q] Magnetic car mount causes screen to turn off topic

I have the Logitech [+] drive magnetic mount in my truck. When I attach the Nexus 6 to the mount, the screen turns off. If I try to turn the screen on while the phone is magnetically attached to the mount, the screen will immediately turn off. As soon as I remove the phone from the mount, the screen will come on. Does anybody know if there is a setting that controls this behavior or any kind of work around (i.e. Tasker, etc) so the screen will stay on when attached to the mount? I would like to use the phone for navigation, but that is obviously out of the question unless I use a non-magnetic mount or just leave the phone loose in the console, which neither option is preferable to the ease of the magnetic mount. Any help is appreciated.

Thanks
