My navigation est. time of arrival is off one hour. How do you reset? If i should arrive in 20 min. it says 1 hour 20 min. The clock in car is correct.

It is probably set to daylight savings time. Check the setup menu. It is unfortunate that you have to remember to do this twice per year.

There is a way to adjust your average mph in the NAV system. I don't have the manual readily available, but I did it about 1 year ago on my car. For example, you can go in and adjust your speed on highways to 60 mph, other roads for about 40 mph.

Therefore, the Nav system knows what your approx. speed is and how many miles to the destination, therefore will give a more accurate calculation.

Check the manual, it should be in there.
