I want to change the stereo in my 2013 Tahoe from a basic CD player to the best factory one with nav, is this possible? I have a 2013 Ram that came with a basic stereo and I bought a touch screen without Nav from a wreck and it plugged in and worked without a problem,even the Sirius was still working and did for about 6months, even one with Nav would have worked but I couldn't find one at the time. I want to know if this is possible with GM's because I know where to get one for the Tahoe with Nav.
