2011 Edge Limited with nav. After the s/w upgrade, when programming a trip there are two problems dealer can not fix. A trip is programed using mostly interstate driving. After approximately three hours of driving, nav system will give directions to turn off the interstate and wants driver to drive on surface roads that do not go to final destination. If turn command is ignored, system will recalculate using original route. But then this is repeated several times during the trip. It makes no difference if shortest route or fastest route is selected. Had I not been familiar with the programed route who knows where I would have ended up. Unre;iable navigation system. No problem prior to upgrade.
Additionally when driving the interstates, the split screen should show distance and time to the upcoming turn offs. Distance is shown but time is not. Only shown as 00h:00m.
Is anyone else experiencing this?
