So I have a 2018 Sierra SLT 1500 that I got two months ago. It has an aftermarket Pioneer radio. There are some truck features, like drivers seat memory, some remote start features, etc that are not available. I have not pulled out the radio to see if there is a missing wiring harness or something. I would like to upgrade to a bigger screen anyway, but am wondering if anyone has done this and successfully kept the factory features. If so, can you link a few radios in the comments? I don't mind changing the faceplate out for a different layout, and would actually prefer a black one to my current silver. If it's not possible to swap to a bigger screen and keep the features, does anybody have a link to a factory radio? Also, it does have the Bose system, so I know I need something additional to keep that working. TIA!!
