A comment...

I had a Garmin Nuvi, and it was a great GPS, but had it in the Cobra at a BBQ in the middle of summer - left it in when we parked because we could see the car.

When back in the car, the GPS booted, then died. The battery actually melted! And Garmin would not repair because the manual says 'do not leave in the sun' - a product 'designed' to mount to a car windscreen! (and replacing the battery did not work).

So always remove them from the Cobra.
