fuel economical option on Garmin nuvi 255WT

[ellenbetty]

I just updated the software of my Garmin nuvi 255WT. I noticed a option I do not remember seeing before. Fuel economy navigation. To choose the fuel economy option I had to program the city mpg and the highway mpg of the Yaris into the navigaton system. Has any one tried the fuel economy option before? Like or dislike?

This is the "ecoroute" feature they put into many of the newer Nuvis in an update. It's mostly a gimmick. It's not very accurate, even if you put the actual city and highway mpg you get.
