Well I ended up having a play with one of the Gizmos this afternoon whilst waiting in the hospital car park for the Missus appointment.
I downloaded a couple of those 50/60's 'Look at Life' youtube videos onto a USB stick to play on the infotainment system, Stuck it into the drivers side USB port & the system picked it up straight away & played them
I read some people were having difficulty playing video/music formats on USB sticks, I've no idea what format I downloaded the videos in from youtube but it worked perfectly,
I can kick waiting rooms into touch now & relax in the car watching videos
