Wondered if any one else has had this problem. My media system started turning itself off a couple of times when the stop/start activated or I changed radio channels using the touch screen. Would come back on after 4 mins or so. On a longer trip last week it turned itself off every hour or so for a few minutes then came back on. The following day it wouldn't come on at all and has been off since. Booked into the dealers on Thursday to get it looked at.
