We are finishing day 14 on the road .... we have logged on 5,100 miles thus far. Mileage has been as high as 27.4 at 60 MPH, but anything over 75 MPH will net you around 21 -23 MPG, depending on winds. 70 MPH seems to be the "sweet spot" with the Traverse .....making good time without losing all the good MPG numbers. We have been into elevations of 12,000 feet, have had 19% inclines, the Traverse has performed in a flawless and able manner.
As I wrote before TBT has been a problem the entire trip. In Wyoming the TBT stopped downloading to our vehicle. Tech assistance (Tim ) was able to do something yesterday ( Saturday ) to get it up and running again. It has worked Saturday and now on Sunday.
You folks north of the border in Canada ...hear this. Some of the navigator advisors are less than knowledgeable, some are rude, some hang up ... it has been a challenge. However, a young lady from Toronto, named Shannon, is the navigation advisor of the year, in our book. When our TBT was totally out, she supplied us with taped directions, made hotel reservations for us, contacted tech support for us, actually spent 20 to 30 minutes with us the other day.
Onstar has centers in Toronto, Detroit and a city in South Carolina. She was the most polite, compassionate , helpful person we have met on Onstar, and she is a Canadian! Way to go up there, folks.
