its; really fabulous…

The best thing you can do to prevent it from happening again is to run the Garmin WebUpdater (linked in the article above). Garmin routinely release firmware updates to combat signal acquisition issues like that.

If you continue to get issues where the signal “goes nuts” like that, turn it off and turn it on. Even if it’s in the middle of a route, on restart it will pick up where it left off without the need to plot it again. 99% of the time this will clear out signal problems unless you’re passing through a mountain.

Would agree with all you said,

but

while coming over the lower 59th street bridge yesterday my garmin 255w thought I dropped into the east river!! Then it tried to route me through Roosevelt island– !!– then, when i made it to Manhattan it didn’t know where i was, “take next right on 23rd street”!!

Lucky for me i didn’t need it anymore cause i knew my way, but i couldn’t take the time or my eyes of the road to shut it off (ya know it is manhattan),

so anyway, it just kept guessing and telling me weird directions, even when it figured out where i was. I ignored it for a couple of minutes and it finally it freaked. I mean it froze up, like the computer at the end of “Desk Set” or any number of 60′s TV sitcom episodes where smoke starts blowing out from the magnetic tape and blinking lights.

Is it Nuvi, or do all GPSs lose it in tunnels and underpasses?????

I’m worried cause what happens if it does this when i’m going to Queens?!!

I’ve missed my 14 day return by 2 days, and would love to know if i made a bad choice. Is this an unavoidable problem with all gps companies?

thanks!

I once owned a Telesystem GPS which had a much worse user interface of the Garmin but gave me weird routes only a few times, while the Garmin gives me weird routes a little too many times in my opinion.
