You need to get a better GPS if yours won't see through a bimini. My
8 year old GPSMAP 175 works 99% of the time under our hardtop. Every
now and them I'll get a "weak signal" for a few seconds, but its never
enough to affect our navigation.

What I'd like to know is how the nav unit on my wife's new Toyota
stays on track in the Big Dig, 100 feet under ground. It seems to
wander a bit, and then it snaps back into place. Is it cheating by
assuming we stay in the tunnel?

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.

The onboard navigation equipment worked well. The handheld Garmin GPS did
not work inside. As for the Magellan Gold it did the job good. My friend
had to stay close to the glass windows. My question is if one has to pick
up an handheld GPS which one will it be?
