I see them on eBay too, but how or where do they get programmed

Awesome! So it’s pretty easy then, not to step on toes but what’s something like that cost the hmi?, I use pandora all the time and carplay for the maps, so I’m not worried about adding factory nav

Iv been reading on this and it’s got me so confused, I have a 2016 ltz without factory nav, and no car play option or pandora, all I want is car play. So all I need to do is upgrade my hmi to the 2.5? And does it need vin programmed or not? Where do I find these at!? Attached is the picture of what my home looks like now.
