The center display between the Speedometer and Tach, I have set to the digital Speed, it works fine but sometimes it will go black for a few seconds and then come back on. The 8.4 touch screen is not affected. I did try the navigation system out and it would show up in the center screen but would freeze at a turn until I would use the select buttons on the steering wheel to cancel it by going back to the digital speedometer. Has anyone else had this problem with the thing going black and coming back on? And is there a fix for it? I have had the Jeep for 3 weeks now. Maybe some setting I have overlooked. I checked the software and it says it it up to date. Thanks.
