The MFD shows 27.9 but I also check the actual fuel usage which tends to vary from the MFD. Last time filled up I had traveled 417 miles and used 14.8 gallons which averages about 28.2. As for the temperature here in Denver the highs have been in the 80s and 90s since I bought the car.

I live in Denver so perhaps we are blessed with the higher altitude but with about 3000 miles on my 2007 400h I am averaging about 28 MPG on 85 octane. I have tried 91 octane a few times but did not see any difference in MPG or performance.

But has anyone installed one yet if so how much trouble is it to install? I tried to get them to send me the installation instructions to see for myself but I never really got a straight answer.

The DVD Drive is located in the rear cargo area under the floor where the tire tools are located. It is on the right hand side in a trianglar shaped area behind a panel. The panel is on the right rear most side. Behind the panel you will find a slot loading DVD drive. There is a small switch on the top left hand side of the drive slide it to the left and it will eject the disk. You may need a flashlight to see the switch. TYou just insert the disk back in to reload it and return the switch to its original position and replace the panel. As for getting new nav disks the only other place I have seen them is on eBay. If you have 6.1 you have the latest that I know of.
