Ok so I have been doing so checking on the forums and just trying to find out for sure what I need to purchase. My truck- 2015 2500hd build date is 12/14. Radio is a IO4 and 4.2” my link with back up camera. I’m wanting to go to an 8” screen and want to have Car Play to use the Waze App. So this is what I think I need, buying off eBay and then prolly send to magpie. Can someone verify this and tell me if I need anything else or what to do? And do I need to have the vin programmed to mine? 84222864 radio receiver from late 2017. 84364934 2.5 HMI 8” touch screen my link.
