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!

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.

Update: I had the module removed for a day to peek inside to see if perhaps it had a fuse I could replace, or a burnt component. I noticed a couple LEDs so decided to see if those would at least illuminate. I plugged the module back in and it came to life! I went to my email to respond to Cruz tech support that it was working again and found they had answered my message to them. They said, “Try unplugging it for 15 minutes”. So now I know if it ever does that again to pull the radio fuse for awhile to reset the Crux. I used this to install an aftermarket head unit in my 2005 Silverado. It worked great. It chimed, it sent the accessory power and reverse signal to the head unit...all good. Then I jump started my truck with a battery pack and after wards, the head unit wouldn't power on. I could reset the HU and see that it powered its USB ports for several seconds, then it would turn off. I thought the HU had an issue. Probed the power leads today and discovered the Crux is no longer sending power. Also realized it wasn't chiming. All the fuses are good and there is 12v constant still. So apparently the jump start fried the Crux module. (It didn’t, see update)

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.

Fits good for 2006 gmc Yukon Denali with bose (y91) amp. Just connect wires ect and make your harness then plug and play with the right dash kit. This kit comes with the antenna adapter needed. Chime is annoying, I turned it all the way down. Make sure to set your dip switches to the correct settings for whatever radio brand you have. Was pretty straightforward. So far so good. Been a week or 2

I installed a Pioneer head unit in my 2003 Chevy Trailblazer with Bose premium speakers. I purchased this interface and it only works sometimes! While driving the sound stops and the only way to get the sound to start playing is by pulling over, shutting the vehicle off and restarting the vehicle!? Sometimes you have to restart multiple times or you have no sound at all. Terrible product!!!!!!
