Does it hurt a radar detector to be in the sun all day?

My Valentine 1 radar detector sits in the sweltering heat in my car all day at work. Will that affect it? Does direct sunlight affect it? Or do I have to take it down every day?

Sunlight itself is unlikely to affect a radar detector but excessive heat (produced by exposure to direct sun) can make it fail sooner than if it were kept cool.





Solid state electronic devices have a lifespan which is related to the temperature at which they're operated. The hotter they are, the shorter their life.





It makes sense therefore, not to leave your detector exposed to sunlight if it causes the case to get so hot that you can't touch it without feeling pain.





It's also a good idea not to leave your radar detector in plain view like this because it invites theft.

It's not good to leave any electronic device sitting in the sun inside a hot car all day. I would move it, if possible.





One solution is to use a visor holder for your radar detector. (I added a link to one in the sources, below.) A visor holder keeps your radar detector up high, above your head on your visor. In addition to keeping your radar detector out of the sun, a radar detector visor holder also elevates your radar detector, providing even better radar detection. If you use a Beltronics or Escort radar detector, there are additional accessories that allow you to connect a hidden power cord between your visor-mounted radar detector and your power source.
