They should have a yoke mount for the 2210. They sell a package incl. aviation software and GPS.
I have their yoke mount and I used to use an IPAQ 3630. I used the "dummy" sleeve that came with the Ipaq and used velcro to attach this to the yoke mount. I now have an IPAQ 1940 and I purchased a cheap case. Once I get it, I will modify it and attach it to the mount.
I know that the 2210 does not use expansion sleeves, so I do not know exactly how the yoke mount works from control vision.
Anyway, check out the software while your'e at it, it's rather extensive.
Good luck !
