Updated model allows a Tablet in a rugged case (Like Samsung A7 Lite) to be bolted to the lower portion or a RAM ball mount with AMPS bolt layout to be bolted in 1 of 2 lower locations maybe for a Garmin Zumo XT or an motorcycle Apple car play device. This model includes an Upper RAM ball 1" style mount to attach a GPS above the stock gauges. Note ball may benefit from electrical tape over it to make it grip better and slip less. Could also use upper ball mount for a Go Pro type camera
