I’m upgrading from the 5” screen to the 8.4” with navigation and want to make sure I have everything I need. I already have Alpha OBD and the bypass cable to enable dual climate control, so I don’t get the hot air issue. My current setup is single climate without SXM. I picked up the 8.4” display with the radio code, dual climate controls, and matching module from Marketplace, but I don’t have any harnesses. From what I understand, I’ll need one harness to connect the screen to the module, and another for the GPS/nav. Can anyone share the part numbers or a link to the correct harnesses I’ll need?
