dunno dude. I saw one for £50 i thought might be handy for a spare.
did think about a rear view camera I can servo control to looka t fitties in traffic jams. It is always hard trying to perve on fitties in car behind using your rear view mirror!!!
Theya re jsut about 1" thick and wont match my other sunvisor so i might get one and hack my sunvisor apart and fit it in there. Just doing the screen int he dasha t the moment. My damn dash is too long to puch my HU back enought - gonna have to trim some fat from places inside the dash....out comes the dremel!
