agreed, the UV will degrade the display and the controls..

If these units are flushmounted there would be little or nothing explosed to
the sun when not in use.

I didn't install mine in the cockpit but just inside the companionway
hatch.. This gives me ready access yet secure from theft or damage. I'm
always concerned about damage from spray and the claim of waterproof
satisfies these concerns.
