I have set my fuel cost to what I last paid, however when I get my information screen after shutting off the car the savings always says $0.00. What am I doing wrong?
You have to give it a MPG to compare it to... if you leave it set as default, you won't be comparing anything, so there won't be any savings.
Go into the settings and enter the mpg data for the vehicle you want to compare it to. Otherwise change it to the non comparative mode and it will give you your trip cost as you drive.
Settings -> Eco Savings From there if you select the comparative MPG and reduce it to zero, it will display OFF as the number. Although if you didn't have anything in there to begin with, I would think it should have defaulted to off? Also I prefer to have it set to basic mode, where you get the HSMI on the screen.
