Moving between the driver and gunsight and magnification and interior picture positions
To move between the interior pictures and to get to the gun sight and to adjust the magnification of the gun-sight (if the gun-sight has magnification settings, many do not) you need to map the + - (plus and minus keys on the keypad) keys to this function. I think they are set to this by default but check.
