Just got a 2010 LR2. Does the trip computer have a break in period? First tank of gas was 70% highway and the MPG was way off. I calculated 18.4 mpg, it was saying 24. Does it get more accurate?

How is the range calculated? Mine floated all over the place. I'm assuming it takes some sort of average based on speed.

Thanks
Kevin

 

Another thing...if anyone knows how to change the trip display to 12-hr time from military time that would be great. I would have thought changing it in the radio would change the trip, but of course not...
