The central panel for the GMC Yukon's radio, navigation and entertainment system is just too small. There's plenty of room to accommodate a larger unit with bigger buttons that would be easier to find and use while driving. Seriously, what's up with the tiny volume and tuning knobs? Good luck turning those with cold fingers or when wearing gloves. The touch screen radio and navigation system is easy to use and entering an address takes little effort. I also loved the backup camera that displays the view rearward on the screen when in reverse; however, GM should consider incorporating a swivel feature that allows the camera to turn with the steering wheel for a better field of view side to side. The entertainment system is initially confusing but takes just a short time to figure out as I discovered when my daughter asked to view a DVD. With the push of a couple of prompts on the touch screen, I handed her the remote control and headset and resumed listening to the radio while she watched a movie making us both happy!
