Pros:- Works.- Box contains everything you need to wire your aftermarket head unit into your vehicle!- Wires are long enough, thankfully- Slim design, not obtrusive within dash, easy to tuck away.- Optional chime module. If you don't like the ""door ajar"" chime, guess what! =)- Two ports for harness, one for Not-Amplified, one for Amplified. If you end up needing to crank volume up to HEAR anything, chances are, you got the wrong port.Cons- The selection switch, for aftermarket head unit control, and chime volume could have been better designed. The chime module volume, for instance requires tiny (really tiny) screwdriver, and guesswork, squinting back and forth from documentation to box.- Box has no anchor point for a zip tie or screw. Get creative.
