The Metra LD-GM29B is a steering control interface harness designed to enable the use of aftermarket radio systems in GM vehicles (2006-2017). While this harness can be a valuable investment for those looking to upgrade their in-car audio system, it is essential to consider both its advantages and disadvantages before making a purchase.
