Even with your settings, Route 1 and 2, do not go the way you wish. True is looks that way, but if you hit route 2, then on map screen go to the right side (3 arrows/lines), tap on that, then at the bottom under Route Display Options, tap on Highway view. You will notice that I-70 is not your primary route.

Going back to Post 6600, with those settings you will see the route you are wanting.

Now I do understand the "ReCalc" issue, I am looking into that. I think that might be giving the I-80 route on a unplanned stop.

But, based upon your settings, the 720 is giving you a route. Change to Freeways - Prefer and Shortest will route you the way you want.

ROUTE - FASTEST
FREEWAYS - ALLOW ALL

I know you were on I-70 for your route, but with Freeway - Allow, I-70 is not considered a primary route, I-80 is.

I am looking into this also.

A lot of factors go into how a road is rated and what classification is given. You see a road, the database sees a bunch of settings that are in the map data for each segment of road.

I am still looking into the Truck stop issue of the closed exit.

"I called in about 6-8 weeks ago because the unit was doing strange things - I believe I visited with David. Whenever I am headed west, the routing on the unit gets odd. I can be running an obvious I80/I76 route from PA to Denver, and the thing will want me to drop down onto I70, adding almost 200 miles - not shorter OR faster. It will also want me to go north into Chicago and then take I88 west to Davenport rather than staying on I80 to start with. Dave agreed that there was something odd going on. He suggested I experiment with the Prefer Interstate and Avoid Small Roads settings, and that if it didn't improve he would replace the unit."

I need the start/stop locations.

"Last week I was heading west on I80 in IN. Planned on getting fuel at the J in Lake Station, but exit 21 on I80 was closed. No problem.....I got on I57 south, and reset the next stop to the Petro in Gary, IN. Got onto I80, the billboard said next exit and the 720 agreed. I've never been to this Petro, so I was relying on it to get me there. It said to head north off of the exit. It kept acting like the Petro was roughly 2 miles ahead. IT LIED. I got to where it took me - into a freaking residential area!"

I am not understanding this one. You are in IN going West, but you say you got on I-57 South. I see I-57 being in IL.

The Petro is on Exit 9 on I-80 in IN.

I can place myself on I-65 and route to that Petro to see what route it gives me. But being in demo mode I wouldn't be able to duplicate your routing exactly.

This is being looked at. I know what the issue is. Turning off ReCalc might help you. It will retain the original routing if you pull in to a truck stop. The original routing will show up and once you are back on the highlighted routing it will continue.

I-70 as primary route meaning in your PA-CO route it was not in the routing with each setting I tried until I hit the one combo. Less than 150 miles on a freeway that goes cross county is not a primary route to me.

What the compare routes shows is at a distance due to the length of the run. If you looked at the detail routing you would see that I-70 was not primary.

Nothing wrong with your TND. Based upon the settings you have and the way it compares routes based upon your settings, it routed you the most legal way. Why it picks I-80 over I-70 I have to find out.

Thanks,
