Many thanks catymag for putting me straight on that point, i guess how i read it i thought it meant you need to flash the firmware if it was GVS=YES, my mistake and i will make sure i ask questions before go ahead again. still no harm done just a little frustration at my end.

Once again many thanks all who posted.
