OBC issues

If I push in the BC button and hold it down, the cluster info. screen says PROG. Now in the nav/radio screen it will display OBC options you can program - consumption1, average speed, etc.

Use the rotating knob on the bottom right of the nav/radio screen to navigate. Push down on it to select and put a check in that option box. Then navigate to MEMORIZE to save your selections.

You can use the BC to remotely cycle through the options you selected and it will display in the cluster info. screen. HOWEVER, you can't reset an option/function using the BC button - only display those options you programmed to display.

You have to go to the nav/radio and select MENU, On-Board Computer. Then navigate to the function you want to reset (right button again), then push down to select it. Then a RECALCULATE prompt appears. Select this and it will reset that option.

I believe if you don't have the nav screen, then maybe you have to clear the functions in a similar fashion - through the radio/OBC buttons. I also assume that the OBC functions can be displayed on a mini-screen (same one that displays the radio information).

You are the man. Same setup on my car. 4.8, nav, dsp. I did not see the Recalculate prompt before. I also did not notice the nav switching over to the program function after holding the BC button. Really cool, definitively not intuitive.

Thanks again, appreciate you taking the time to figure this out. Finally going to see what my consumption is after the maintenance I've done.
