The older (pre-Topo 2008) topos had better representations of the close-to-land ocean waters than the newer US Topo products . Of course, such objects as buoys may have been moved since the maps were made...I want to mention that if you're thinking of using the GPS for paddling on the ocean Charts and Maps are two different things.
USGS topos are public domain, thus no locking. The routeable road maps contain copyrighted data and thus the mapmaker can demand per-user fees from Garmin (and the other consumer GPS suppliers) which is passed along to the customer as locking fees. (One lock currently comes with the original purchase.)Garmin topo works fine straight from the box...no hidden fees.
Garmin City Navigator needs to be unlocked...we returned it as soon as we saw the UNLOCK word.
There used to be a version of City Navigator which was not locked, but it also does not allow automatic routing on the GPS. (It can auto-route in Mapsource.) Perhaps it is still available. I avoided the whole issue by buying the last set of routeable road maps (Metroguide, v4.02?) before locking was applied due to a change in the map supplier. Of course, the map is old, but all maps have errors...
