aftermarket

Has anyone here installed an aftermarket stereo in a 2017 Chevy Traverse Ls Model?? I tried finding a video on it but can't seem to anything for an aftermarket radio for the 2017. Any leads or ideas will be very much appreciated.

I have a 2015 Traverse LT and have recently purchased a travel trailer. Our Traverse did not come with the manufacture's tow package but I have been adding the pieces for the last month or so. I'm hoping someone can look over my list and let me know if I'm missing something and any general...
