I think there is also a difference between cgpsmapper maps with address 
search (like slovakia topo) or garmin own maps, as cgpsmapper homepage 
states that address search is only working if exporting via Mapsource as 
mapsource will create on exporting the address search index. Using 
sendmap it will not work. I don't think garmin's own maps have the same 
"annoyance".

Address search is really the last "big" thing we're missing.
