Sorry if this is posted elsewhere; have searched and searched, but can’t find anything recent that answers the question:

Where (if anywhere) is there a list of the GPS windshield mount laws for each of the lower 48 states? Thought CA and MN were the two “no no” states, but in doing a Google search, I’m coming up with lots of conflicting info about if, how, where, etc.....

Thanks in advance for your wisdom, Oh Great Ones.
