730 GPS Help Needed
I have the 730 w/GPS in my 2012 Grand Cherokee. For some destinations, the routing and Estimated Travel time functions work well. But for one destination I am very familiar with, it does not provide the optimum routing, and the estimated travel time is about 40 minutes longer than the trip actually takes. I experimented last weekend by stopping the navigation and reentering the destination periodically along the route. After a while it did start identifying the optimum route, but the time continued to be way off. When we were 3 miles from our destination it said we had 30 minutes to go; I reset it and it still said 30 minutes. I get the same routings and times whether it is set on fastest route or shortest route, and no other settings change the result. The dealer confirmed that I have the latest software. He also entered my destination in a 730 in another vehicle and got identical results. When he entered the destination in a 430 in another vehicle, it gave the optimum route and correct estimated time. Does anyone have any recommendations? Thanks in advance!
