Go into the diagnostic menu.
To do this, press the power button so it's on. (acc is fine, you don't have to start it.)
Hold the INFO button on the Nav, then turn the headlights on and off three times. (actually, parking lights are fine.)

You should now be in the diagnostic menu.

"Somewhere" in there is a CAN connection check. I think it may be under the "Navigation Check" menu item, but not sure. The manual is really bad on this.

Try pressing the "Menu" button on the touch screen to get to the home screen, then press the "Display Check" on the screen, then press the "Vehicle Signal Check" button on screen. That should show things like battery voltage, park brake on, speed, etc., but somewhere near there is a CAN check. If it's not in this menu, it should be in there somewhere. If you find this menu, if you can let me know how you got there.

What I'm looking for is a screen that says "CAN Connection check", and will probably say CAN Connection OK. This screen does not exist in my unit, and I think is the key for the energy screen.

One last check while you are in there. Get back to the home menu. Press the "Navigation Check" button on the touch screen, then press the "Parts Information" button on the touch screen. Let me know what numbers are in there.

I think the first part number is the firmware, and the second is the disk.

Mine is:
NAVI Information
DENSO
1650

Disk Information
DENSO
V06.05.11

I suspect the first number might be different in the units for hybrids. The second may be different depending what version of disk you have.

To get out of the diagnostic menu, simply hold your DISP button for about 3 seconds and you'll be back to normal.

Thanks in advance!!!!!!!

It will really help narrow this down.
