hi,, i am new here.
i have a 1999 ml430 . all of sudden my trip computer doesn't come on.
i don't know how to make it back on.
after that when i turn off the ignition ,radio doesn't go off by itself.
i need to turn it off by pushing the power button to off the system.
help....

 

Maniack,
For the trip computer, try pushing the mode button and see if if comes back on. Each time the buton is pushed it changes through the different modes options then to "off".
Good luck, I hope that works for you.

 

Check your fuses for both problems, sorry I do not know which one but another member may.
