Sailorman Report post Posted October 29, 2010 I have a 2010 FUSION HEV with factory Nav. I've noticed a few quirks with trip routing directions that the unit provides. Has anyone else had similar experience. I'm used to Garmin and Mapquest routings and noticed on a couple of occasions very different routing provided the factory NAV unit. Seems to be very biased to travelling on interstate highways to the point where it doesn't recommend any shortcuts off the interstate using secondary highways. Routings from the Navteq website are also different than what are provided on the unit in the car. Seems strange. Recent experience on a trip from Toronto to Annapolis was a routing to Erie PA and down I-79 to I-80 and east to Annapolis. Garmin and Mapquest provide completely different routings. Anyone else had similar experience or can offer any explanation or suggestions. Quote Share this post Link to post Share on other sites
Waldo Report post Posted October 29, 2010 It depends on the speeds you have set. In the Nav settings, you can adjust the average speed for each classification of route. If you speed up secondary roads and slow down interstates, it will adjust the route to give you the shortest time. Quote Share this post Link to post Share on other sites

Have you set yours different than the factory presets. The highway speeds must be set high and secondary road too low. I tried googling to look for some optimal settings and couldn't find anything.

Just tried to adjust the speed settings, but it doesn't retain the new settings. There's nothing in the manual on how to save these settings. WHen you change them and go back to the home screen, then return to check the settings, they've gone back to the previous defaults. There must be a simple explanation. Any info would be much appreciated. Quote Share this post Link to post Share on other sites
