Does anyone know if Ram makes a mount for the Montana 700 series? I mount them on ball heads in my boats and side by sides. I see some pricey ones with wiring kits. All I want is the holder that attaches to the ball mount. Not seeing anything on the RAM site? I gave up looking for a belt holster. Garmin made them for my montana 610. Evidently not for the 700 series? I'm experimenting with Molle pouches instead.
