I checked with Google ... Unfortunately Cholula is correct with:
"Apparently these can’t be legally attached to the windshield in CA or MN. But you can dashboard mount them with either a suction cup or a friction pad/bean bag"

Yes, my Garmin did come with a
dashboard disc. However, I'll still have a problem ... my car in CA will be a rental car....I'll find a way@:-)
BTW, I still remember: in the DDR (East Germany) 99.9% of the Trabis had a "vehicle suction cup mount" with an attached note-pad.
