Sorry, I misunderstood your post. Thanks for the info. Still, it makes my original question even better: I'd much rather rely on Google maps to keep my maps updated for free, but I'd still like to use the Eco routing algorithm.

Link doesn't work now. Anyone know where to find this info?

Well, yes obviously you don't have to update. Only if you want your maps to be up-to-date.

Same here. I'm at 28k miles, 44 mpg, and I don't have any flowers. Maybe the 2015 is different than the older models above??

I have ~28k miles and haven't reset my mileage indicator, so over the life of the car, I've gotten 44.1 mpg so far. But it took me a while to adapt my driving style, so that number is going up. I routinely get over 50 mpg now, generally 52 to 55 mpg on most tanks, though I admittedly drive VERY conservatively. I always take the surface roads for local trips rather than highway, drive a little under the speed limit (42 mph), brake well before lights, etc. I've only recently realized what a big effect the A/C has on mileage. (Duh.) So whenever I can tolerate it (generally just in the evening, since it's summer), I've been turning off the A/C and just going with cracked windows, tilted sunroof, and the car's fan. This adds close to 10 mpg to the mileage. All mpg estimates here are from the car's computer, though I've noticed that that seems to overestimate mileage. My calculations are usually 2 to 3 mpg lower. Here looking to see if I can pick up other tips. I'm also wondering if anyone knows of iPhone apps for navigation that might give an Eco route comparable to the one the car has; I'm not thrilled at the prospect of having to pay Lincoln $150 every year or so to update the map. That really should be free, IMO.
