i bought my D3 from Crutchfield, just to get all the free install parts, so i could install it one day, and not be buying parts all over.
i got the free BOYO back up camera, it worked pretty good (maybe a bit dim?)
i took the truck to a Quarter-Squirter and washed it,
and it got damp in the camera lenses, and it fogged over.
called crutchfield, they emailed me a UPS label,
boxed it up,
had brand new one back, in just a day or so.
good deal.
