Thank you for any advice you can offer:

My 2004 MDX navigation screen works fine, but the trip computer doesn't compute. Where it should show MPG and range, I get dashes instead of numbers.

Any idears?

Thanks again!

I have navigation. The GPS works great.

The MPG shows no bar.
Range shows ---
Trip shows 2.8 (but that is wrong)
Average MPG shows 22.4 (which is probably right)
E/T shows 0:06 (which is wrong).

Reset Manually has RESET highlighted
Reset with refill has OFF highlighted

It won't let me reset either of those.

Thanks for your help!

You can do some diagnostics on the system, and I suspect you're going to find something wrong with the FCAN communications, but I suppose it could be a sensor (fuel pulse sender?) too.

You can get into diagnostic mode by pressing and holding the Menu, Map/Guide, and and Cancel buttons for five seconds. Once you're in diagnostic mode, the menu looks like this:


Good luck!
