I've always been directionally challenged and have always relied heavily on GPS to get around. I was an early adopter when they were little more than a moving map, on a tiny map, at a cost of $2k. I was looking at my "new to me 328 GTS" and see no obvious place to mount a phone holder and don't really want to glue something to the dashboard. I am thinking about getting one which suction cups to the window but can't thank of anything better. Has anyone come up with a novel solution?
