Product seems fine, but doe NOT fit my vehicle as Crutchfield said it would. While this has one pin for amp, and one for the micro antenna connection, my vehicle has to such micro antenna connections and one amp pin. ...therefore had to cut the casing of the connector. No instructions provided either... not that it's complicated, but nothing.
