Is there any law in California that restricts mounting a GPS to the windshield such as a windsheild mount?

If it is, is my only option a dashboard mount to my GPS device?

Yes, California Vehicle Code section 26708, subdivision (a), paragraph (2) provides that: “No person shall drive any motor vehicle with any object or material placed, displayed, installed, affixed, or applied in or upon the vehicle which obstructs or reduces the driver's clear view through the windshield or side windows.”

Personally, I would go with the windshield mount. Worst case scenario, an Officer issues this correctable equipment violation. Switching to the dashboard mount and paying a $10 fine removes the ticket. But if your reception is just as good as the windshield mount then you may as well just want to go with the dashboard mount in the first instance.

According to the CHP, the California Vehicle Code does not prevent the use of a suction cup for mounting a GPS unit to the front windshield as long as it does not obstruct the driver's view or create a safety hazard. http://answers.yahoo.com/question/accuse_write?qid=20071115231712AAIBgfU&kid=RpIuWTe0ADkGC7xp0hk1zqAF2erEr_ox_BGvMkpE8m0UeWLS2Ut6&s=comm&date=2008-04-07+11%3A12%3A13&.crumb=
