An accessory holder system for securing a Personal Electronic Device (PED) for use in a golf cart whereby a golfer can easily view golf course GPS information on a display. The system includes a mount for insertion into a golf ball holder disposed in a golf cart; and an accessory holder for attachment and adjustment of the viewing angle of a PED in a variety of golf cart configurations. The accessory holder is typically composed of a mount with an attached rod for displacing an accessory away from interference with the golf cart dash board; a ball joint with a tensioning cap attached to the rod for adjusting the viewing position of an accessory; with a platform for mounting an accessory attached to the other end of the rod. The mount includes surface features which provide rotational stability for an accessory holder without relying on a friction-fit.
