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 does not complain about anything at all and its tone is clear The kit is very clean and I only used it for sound I paid: 4143 and I have proof of that And your safety. For offers and please do not undervalue the item because I did not use it much and the car itself is mostly parked and does not move, meaning the kit is almost new.
