Hi all, new to the forum and have been reading all the great posts. Thank you all. I just got my first Sprinter 170x 2012 ERA MB. It has only 4,500 miles. Right off the bat I noticed that the infotainment touch screen only works on the right half so when I try to use the modes that are on the right side I can get them, but on the left side of the screen I can't. Playing around with the remote and I can cycle through to those, but then still have trouble when the GPS mode or radio mode is up. I'm hoping someone has a solution as the replacement cost means changing out the whole system (can't get the touch screen only) and hoping that it might be a easier fix like a connection of something??? Anyone?
