2010 GPS Settings

[hockeyman2000]

Hey guys just wondering if someone has played with settings on GPS. Its hard to find info when you dont have a owners manual thats not a dvd. Anyways here was my experience for around christmas on a trip to Fort Sask by Edmonton from Medicine Hat. I entered it into my GPS before we left Medicine Hat. It showed me the route using Hiway 1 then Hiway 2 (main route I guess) Then decided to take hiway 36. After it told me to do a u turn I stopped routing then proceeded on hiway 36. After about 10 minutes down that hiway I mapped it out again and it still wanted me to turn around. Drove about a hour then told be to take hiway 13 after 36 which was right but was still trying to tell me to take it all the way to hiway 2 rather then turning on hiway 21 for less then a hour. Mean while my blackberry google maps was right on the money. Both devices were set to fastest routes. Not sure if there is another setting someone knows but would be greatly appreciated. Also got into specifics about the hiways as was thinking someone may be familar with them and how stupid I would of been if I took the way the GPS told me. Also on another note traveling at 120km/h except when passing i averaged 23 miles/gal my first hiway trip with my 2010 RT AWD.

Thanks
