Acura 2007 MDX - Owner's Manual - Manual (Page 235)

Your vehicle’s audio system will
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 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.
If your vehicle’s battery is discon-
nected 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.
The system will retain your AM and
FM presets even if power is
disconnected.
