2005 Chevrolet Silverado 2500/3500
Crutchfield Customer Review (What's this?)
Product works as described, other reviews are correct, it is very loud even after breaking the board connection to quiet it down. I muffled it some with some foam and almost sounds factory now. Did have a problem initially because the unit fed power back through the accessory wire making the vehicle think it was still powered up on accessory. Worked fine after installing an inline diode.
Pros: Great option to keep factory chime.
Cons: Loud but would rather have that then to quiet, can always muffle it. Power leaks back through accessory lead.
