It has nothing to do with the traffic function. The traffic function will only change your route if you allow it.
The issue is in the navigation setup. There is an option in the setup for traffic volume which can be set to Light, Medium or Heavy. The default from the factory is Heavy so it way over estimates the time. Go into the setup and change this to Light or Medium and you will get a more accurate estimate. I have mine set to Light and it is much closer to actual.
Anyone who can help -
Grove, thanks for the advice, I changed the traffic to Light and the times now match reality. Except for 2 issues:
- The nav still comes up with way long travel times and avg speeds from Tonopah, NV to Cedar City, UT (this is a trip I make often). It still shows an average speed of 38-39 MPH even though you can easily average 70 MPH the entire trip across the open Nevada and Utah desert.
- My nav will not pick a shortest distance route through Yosemite. This is
100 miles shorter than options through Lake Tahoe and south via Las Vegas. I could only force this route by using the GIS function by pointing at Yosemite as a stopover. But then it estimates a speed from Yosemite all the way to Cedar City, UT of 39 MPH!
What I am trying to figure out is if this is a defect in the particular nav in my car or if it is a major design problem. The dealer (without checking my issues against another Passat with the same nav) says this is the way the system is designed. I don't believe that any nav is designed with such absurd assumptions as 39 MPH across open highways.
Is there anyone out there from California with the top of the line nav (near the SF Bay Area) that can try a trip to Cedar City, UT with Tonopah, NV as a stopover? Or if not from CA try enter a trip to Cedar City with Tonopah as a stopover and let me know what average speed you get to see if my nav is defective or the nav has a major design defect that I need to escalate with the nav manufacturer?
I would like to be armed with the above results before I go back to the dealer as they are trying to blow me off.
Also, does anyone know who makes the nav and how to contact them directly?
Much appreciated,
Rick
