They make wireless models, but I wasn't sure it would work in this application, so I stuck to the HardWire sure connection.
One problem with these is they aren't illuminated. If they'd make one that you can see at night, it would be perfect. I use a small led pointed at it for lighting, which works OK, but it would be better if it were backlit. Slight glare/reflection on windshield is the result.
For less that $30.00 it's a great accessory.
