custom waypoint symbols in basecamp, 62s

howdy. just got the 62s/ having trouble with custom waypoint symbols I used successfully on my old 60csx. They appear in Basecamp (& mapsource) as the custom icons I supplied, but on the 62s itself they are defaulting to the blue flag..

I've copied the relevant waypoint bitmap files to /garmin/custom symbols directory on the 62s, but nowhere in the waypoint symbol menus for the 62s do I see an section for "custom"

Am I missing something?
Or will this have to wait for a firmware revision to the 62s?

tks
