I'm now really glad that I bought this GPS unit. I was riding along on I-44 in MO and saw signs that indicated that there was an accident at mile marker 186 that had the two left lanes blocked, prepare to stop, and expect delays. Wonderful.
Sure enough right about exit 184 traffic was at a dead stop. A quick glance at the GPS screen showed an alternate route through the small town of Rolla that would put me back on the interstate on the other side of the wreck. I took the exit and started that way. As soon as I left the interstate the GPS unit recomputed the route and led me straight through and back onto the interstate on the other side of the wreck and I was able to keep rolling.
The thing probably saved me at least 30 minutes delay time and I didn't even have to stop and pull out my map. Very cool. It was well worth the money.
I'm now parked at the truck stop in Cuba, MO where I am going to have some dinner and get some rest before continuing on to WI tomorrow morning.
