Here's something to play with if you have the Navigation option. Go to the menu, Navigation Setup. Click on Calibration, then Show Version. Now, with the joystick do two clicks up, then two clicks down. You now have a new menu with choices of screens that get into details of the satelites, dead recconing sensors, GPS based digital speedometer and other fun stuff. I am not sure it is good for anything except entertainment, but is it always cool to have cheat codes for stuff. You can check you speedometer accuracy.
BTW did you know that the Australian verison of the CX-7 DOES have a trip computer.
Why not us?
