My E90 is non-Idrive equipped, so was hoping someone could chime in on this. Is the nav loaded off a DVD once, or does it require the DVD to be in the disc drive at all times?
Basically I'm wondering if anyone has had any issues with their nav DVD warping or becoming damaged due to the heat. You can't leave anything inside your car during the summer out here... cd's warp, iPods stop working, small children spontaneously combust. Would the DVD be another thing I'd have to remove each time I drove?
Here it is August 29th, and we're looking at another 112° day.
