GPS, radios now illegal in Jalisco unless orignal equipment

it is mostly about obstruction, things hanging from rear view mirror, radar detectors, gps, sirius radio, dancing dolls,and people who allow their pets on the dash......seen it.
It becomes very hard to see out the the windshield, unsafe and a distraction.
Most vehicles have radios/CD players,built into the dash, those can be distractions.
