ElectriHolstein

Hi, I'm new to the forum, but not new to Chevy trucks. I just traded in my 03 Avalanche for a 20 Trail Boss. I love the truck, but it didn't include whatever package that added steering wheel controls... It has cruise control on the wheel, and that's it. My question is; is it possible to add stock OEM control features to the steering wheel? the cruise is on the left and there's a blank on the right. What I'd like to add is controls for the stereo. I have the infotainment package, and it would be nice to control it conveniently. Why they didn't add this to the package, I'll never understand.. Any help is greatly appreciated.
