Peace be upon you.. I am offering you a kit Type: BTM Fits Sierra - Silverado - Yukon - Tahoe Models: 2007-2018 Usage period: only 3 months, and I have proof of that. Two devices and three remotes are available. The kit has absolutely no issues and its tone is pleasant. The kit is very clean and I only used it for the sound. I paid: 4143, and I have proof of that. And your safety. For sale to the highest bidder, and please do not undervalue the item because I did not use it much and the car is mostly parked and not driven, meaning the kit is almost new.
