## Description

Review: Works Perfectly – Retains All Factory Features! - The CRUX SWRGM-48 made upgrading my GM radio so much easier. Installation was straightforward, and everything worked exactly as promised. It retained my steering wheel controls and the factory chimes without any issues, which was really important to me. I’m especially impressed that it works seamlessly with both Bose amplified and non-amplified systems. No glitches, no static—just smooth functionality and a clean install. If you’re replacing your factory radio and want to keep all your original features intact, this interface is a must-have. Highly recommend!
Review: Works for a 2002 Chevy Cavalier with Non Bose amplified rear speakers - Worked great for a 2002 Chevy Cavalier with Non-Bose amplified rear speakers. This radio interface allows the stock amplifier to work on the rear speakers when replacing a stock GM radio with an aftermarket radio. I also replaced all four speakers with new Pioneer ones. The rears were 3 way and worked using the two main wires instead of the stock GM 4 wires. Important: please note that your car's computer will not work correctly unless you have an interface that returns the input circuits back to the ECM. This interface does complete the circuits on a 2002 Cavalier to keep your car dash sensors running correctly. GM ran some of those key circuits through the original stock GM radio. If you don't have an interface, you cant get your car to run correctly and have an aftermarket radio. Summary: get an interface for your application if your brand requires one to make your cars computer work correctly when installing an aftermarket radio. Its the only way to make your car work correctly with an aftermarket Radio.

### ⭐⭐⭐⭐⭐ 2003 Denali w Bose
*by C***T on February 12, 2026*

Worked for my 03 Yukon XL with Bose utilizing an aftermarket radio. It did come with an antenna adapter, but it wasn't compatible. Buy a separate adapter if same vehicle type. My issue was no sound then around 20 mins of driving the radio sound kicked on. Used multi meter and AI to determine amp was fine. Once I plugged this in to the aftermarket it came on instantly. Takes maybe 10 mins. I used electrical tape.
