In CA, suction-cup mounted devices on the windshield are prohibited. Anyway I think it would be ugly to have something on the windshield like that, but how else could I keep a Garmin Nuvi unit upright? I haven't bought it yet, but it's on sale at amazon and it looks like a great price.

Also, as I live in the desert, my new TCH collects dust like it's autographed baseballs. Is this truly bad for my car?
