My Garmin 48 sees fine inside my fiberglass sailboat's cabin. I always
bring it in at night, and often set it up for anchor watch. It's
always on, and always sees the sky.

Brian is correct .....
NO GPS can 'see' through steel or fiberglass, etc. The antenna MUST
have a clear unobstructed view of the satelites .... no wet sail, no
leaves, no roofs, no dodger or bimini, no steel panels.
