do i have a treat for you!!

1. sit in your car, key inside, press start button once.
2. nav system comes up
3. press and hold info button, while flipping lights switch back and for; you need to get to at least markers lights come up; takes about 4-5 flips - and then magic happens!

this menu comes up;



from it, you can read codes, adjust mike quality, run all kinds of diagnostics, including 12V battery test (mine checked out)

 

oops! sorry for huge pics, didn't realize this forum does not automatically resize them. my bad.

 

if you upload to a sharing site, such as http://imageshack.us/ , you can post links to an optimized version of the image

 

An alternate method is

-Turn on car power (doesn’t need to be started) -Press Map button -Press Silver “Disp” button (bottom right side of display
-A kind of divided screen appears with “Display” on top and contrast/brightness on bottom. While this screen is displayed, do the following very fast:
-Alternately touch the screen under the Display line, then above the Contrast line. Keep doing that over and over until the diagnostic screen appears. There is no icon, you just have to stay under the top line and above the bottom line.
The Diagnosis Menu screen appears –
To return to normal screen hold “Display Button” until Nav system restarts

 

i have no problems resizing pics myself. i did not, as any forum i post to re-sizes them automagically. this one did not. i'll do it next time.

 

so...

anyone knows how to shut down vehicle motion sensor from diagnostic menu? or nav unit menu?
