You need a radio replacement module to retain the integrity of the cars GM LAN data bus, chimes and Onstar (if equipped). They take all the mystery out of the install. You will have to find a manufacturer that has one for these new vehicles. There may not be one for your application yet, which means you need to relocate the original radio and hook up an extra speaker to hear the chimes.sparky
