Review on 📻 Enhanced SWRGM-48 Radio Replacement Interface Preserving Steering Wheel Control and Original Chime Functionality for Select GM Class II Vehicles with Bose Amplified & Non-Amplified Systems (2002-2013) by Marvin Short

Absolute nonsense. Bought this along with a new radio for my 2005 C6 Corvette. After installation the sound on the radio went on and off so I sent the radio back thinking that was the problem. After the new radio arrived and was installed, the same sound problem occurred. I took it to a radio installation company, explained the problem to them and they said all my cables connected perfectly but the key brand was rubbish. After buying another brand, the radio works great.
