I just picked up a uniden mount for a I-phone for 3.50 at k-mart
great little mount with a HUGE suction cup and a great goose neck arm.
cut the I-phone mount down a bit to make it flat and mounted it to the top of my detector
This thing gives you endless possibilities for how you want to mount your detector unlike OEM mounts
I may pick another to modify they are so cheap being it's a clearance item.
