How to attach radio to Techmount?

(I may have this in the wrong section.)

I’m looking at your Techmounts for motorcycles, as I already have one for radar detector and am pleased with it.

What I’m not sure of is how others are attaching a two-way to the top-disc. I’m looking at an MU354R, and wondering if there’s some kind of specific clip or clamp that gets screwed onto the disc for the radio?

I don’t have a motorcycle, so I’ve never used a Techmount myself. According to Techmount, it depends on the device, but it seems many of them are mounted on the mounting plate with hook-and-loop fasteners.

From the Q&A on their web site:

Q. What holds the accessories on the top of the mount?
A. The kits all come with marine grade Velcro (hook and loop fastener) material. This works very well for small flat devices that need to be removed often. (radar detector, cell phones, toll transponders, change holders, garage door openers and small hand-held GPS). Larger GPS systems have several cradles to choose from that will mount to our GPS top plates and adaptors. All of our standard top plates have a hole pre-drilled for camera thumb screws.

Thank you, Rick.
