After seeing this discussion this morning I ran a simple unscientific test on our StreetPilot 7200. We were driving through Glacier NP in our tow car with the GPS. I had left it set for Truck and Prefer Fastest Time. With those settings it routed us around Going to the Sun Hwy, a slow park road with low clearances and maximum 21 foot total vehicle (inc. tow vehicle) length. I then changed the settings to Car, leaving it on Prefer Fastest Time. No change in the routing. Then I changed it to Prefer Shorter Distance, leaving it on Car, and it took us on the park road. That makes sense because Going to the Sun is far fewer miles than routing around the NP on highways. So far, so good.

Then, leaving it on Shorter Distance, I changed it back to Bus,
and then to Truck. In both cases it still routed us through the park on Going to the Sun Hwy! Had we been in the Bird we'd have run into a 9 foot tall tunnel and gotten stuck going around a hairpin turn. It had no data whatsoever about the length or height restrictions, or if it did, the Bus and Truck settings did not utilize them to route us around a road that would have been completely impossible for a 40 foot three axle 21 ton vehicle.

Don't know that this proves anything - maybe the data was simply incomplete for that road - but I have learned to not trust the GPS for much of anything off the interstates. I still use it - it makes a great digital speedometer! - but I read the maps and guides first before I drive anywhere!

BTW, when we got to our campground in Kalispell (Glacier Pines) there was a newer LXi a couple of spaces down. No one home when we walked by, and it's gone now. Anyone
here?

Morey,

My Streetpilot 7200 doesn't have ability to plan for clearances, or even alert for them, as far as I can tell. I do have that feature with my Delorme Road Atlas using one of the DiscoveryOwnersGrou p add-in files. Can you give more specifics?

Thanks,

Gary
