Acura 2009 MDX - Owner's Manual - Manual (Page 239)

Your vehicle's audio system may
disable itself if it is disconnected
from electrical power for any reason.
To make it work again, you must
enter a specific five-digit code with
the preset buttons. Because there are
hundreds of number combinations
possible from the five digits, making
the system work without knowing
the exact code is nearly impossible.
You should have received a card that
lists your audio system code number
and serial number. It is best to store
this card in a safe place at home. In
addition, you should write the audio
system's serial number in this
owner's manual.
If you lose the card, you must obtain
the code number from your dealer.
To do this, you will need the audio
system's serial number.
If your vehicle's battery is
disconnected or goes dead, or the
radio fuse is removed, the audio
system will disable itself. If this
happens, you will see
‘‘ ’’ in
the audio display the next time you
turn on the system. Use the preset
buttons to enter the five-digit code.
The code is located on the radio code
card included in your owner's
manual kit. When it is entered
correctly, the radio will start playing.
If you make a mistake entering the
code, do not start over; complete the
five-digit sequence, then enter the
correct code. You have 10 tries to
enter the correct code. If you are
unsuccessful in 10 attempts, you
must then leave the system on for 1
hour before trying again.
The system will retain your AM and
FM presets even if power is
disconnected.
