So I bought a radio from eBay to hopefully get Apple CarPlay in my 2017 jeep grand Cherokee. I installed it and I’m not hearing any sounds from the back up camera, blind spot monitor, nor radio itself and I’m seeing a message saying hub not supported. I don’t know why and just thought the features are disabled from me not having the anti theft code yet. I called the dealership and the guy told me that I need the same part number from the radio I took out. (68270661AF) The only results I’m seeing when I look are for 2017 Jeep grand Cherokee’s. What should I do ?

Since the radio was from a 2018+ vehicle you also need a new media hub (it sits in the cubby hole at the bottom of the center stack.) There are many other threads here that discuss the part number of the new media hub. The new one has 2 USB ports.
I think your original one has a single USB and an SD card slot.
