Question :

I have an old Peugeot with what-once-was a state-of-the-art navigation system : an RT3 car computer by Magneti Marelli. When trying new navigation CDroms, I encountered an error. The dealer says can it should be fixed by a restart of the RT3 car computer by doing a “Dark button”-reset.

However… no-one seems to be able to tell we where that mysterious “Dark button” is located…

Can you please help me ?

Answer :

There are two ‘official’ reset options for your RT3 car navigation system :

option #1 :

press the DARK-button until the screen goes black and the RT3 then restarts

Note : the DARK-button is not some mysterious unmarked button, it’s simply the button marked “DARK” that is normally used to darken the screen to not shine too bright at night

option #2 :

turn off your car and take the car key out
unscrew the Torx10-screws that are hidden inside the two tiny holes next to the “MP3” and “GSM” printed text (note : the screws don’t come out, the just come loose and stay inside the panel)
pull the menu-wheelbutton to slide out the ‘car radio’
flip open the metal lid that is just above the big barcode sticker
take out the yellow battery pack
unplug the white connector that is halfway the battery pack’s cable
wait one minute
plug the white connector back in, but the battery pack back, close the metal lid, slide the ‘car radio’ back in and tighten the Torx10-screws

According to the Peugeot mechanics, option #2 should work if option #1 doesn’t… Ted nugent.
