PAC LCGM29 Radio Replacement Interface for Select Non-Amplified 29-Bit LAN GM Vehicles,Black,5.00" x 12.00" x 1.00"

I bought this for my son‘s truck that was gifted to him by my father for his 16th birthday. This was a base model 2010 Silverado with a zero options and we wanted to put in a nicer aftermarket radio. This adapter allowed me to replace the radio and retain the ignition key buzzer sounds. However, the blinker leaves a lot to be desired! If the radio is not on at all, you can barely hear this device making the blinker sound. It’s not a normal sound either. I was primarily worried about him leaving keys in the ignition and the buzzer is loud enough to make sure that doesn’t happen at least. It would be nice to see this updated or have an option to adjust the volume of the different features.

chime works like OEM with aftermarket radio

I originally had a PAC GM radio interface for a previous aftermarket radio but I ended up replacing both radio and interface (just in case the interface was dead - turns out it was) with a cheaper grade Scosche interface and I experienced nothing but problems for years. I finally decided to purchase a new PAC interface and I found this little gem. I don't have the BOSE stereo and I will never use Onstar so this option was a perfect fit. After a simple swap out with that awful interface (which despite being professionally installed was still a mess), I am back to original sounding chimes and no more dead battery from the crap previous interface. I'll only trust PAC products in my future installs!

Bought this to replace another that went bad. Just plugged it into the already installed harness. Pay attention to how your radio is wired, it comes with a wiring guide. My Silverado doesn't have radio controls on the steering wheel or powered antenna. None the less, simple to install.

Easy hook up but didn’t work at all.

Works as expected

Worked great on my 07 silverado 1500

I've had this installed in my Silverado for about two months. So far, so good. Easy to install and does the job. I will edit later if I have any issues.

Worked perfectly in my 2010 GMC Acadia (no Bose, no nav)

Installed easy. No issues.

Low alarm Volume ...

Gm interface module melted down and quit after 5 months. Made truck stink of melted plastic and now no music.
