I thought I'd share that problem I have had with my VF headunit. The problem is intermittent and I can't reproduce it on call. Basically if I am listening to music off a USB stick, I have had randomly when I turn off the engine the head unit turn to the radio. If I restart the engine before getting out of the car, the head unit goes back to playing from the USB. Holden updated my MyLink version a couple of days ago, so hopefully this will fix the problem. This video shows the problem.
