Roadmate 2200T update

There was a firmware update made available for the Roadmate 2200T a while
back, the one that upgraded for topographic and marine capability. I have
not yet bought into it Have others done the upgrade, and how did it go?
I'd be interested in hearing any experiences in the update, and in using it
with the topo maps.

Also, was there a street map update in that as well? This would be more
enticing to me. I've been watching all the other posts on map updates, but
there is none available for the 2200T.

Thanks!
