Does anyone know of any way to program the AVICs for truck routes like Garmin? My old streetpilot was great because you could avoid roads and bridges with truck exclusions, but lately I've been running into quite a few and there's little I can do but ignore the direction and wait for a recalculation that hopefully won't run into another one. Yesterday I went way out of my way to follow the AVIC only to find out it was taking me on Storrow Drive near Kenmore square. Not a good place for trucks--too many low bridges. And way too far to work around to where I wanted to go.

Any ideas?

There is a mod and a hack that will work for you but will be a slight pain to implement. Those of us who upgraded to 3.0 have applied the hacked ezrider.exe and IDT's mod. His mod allows you to have a list of "disallowed streets" so you could add each street you don't want to make your route go through just once to the list and you'll never route through them again. This will void your warranty but is VERY handy to have. For example, I go to New Orleans sometimes and I NEVER want to go on the Huey P Long bridge, it is a narrow-laned disaster, so it is now on my "disallowed streets" list.

I was looking up some sys.txt codes and there are references to truck parameters on one of the 'sister' sites. Maybe these will help...
