The other day when my wife was ordering our new GPS unit, the site stated that in you are not allowed to attach anything to the windshield in CA. We are going to be in San Diego and LA in April, and since we will be driving from La to SD and back, I intend to bring along the GPS and V1. I have a method of mounting the GPS in whatever rental we get, but am I or am I not allowed to mount the V1 on the windshield with the suction cups? Just curious, any responses will be appreciated. Thanks!
