Playing a CD
Remove the navigation map DVD from the slot and
return it to its case. Insert a CD partway into the slot,
label side up. The player will pull it in.
There will be a 12 to 15 second delay while the CD is
read, before it begins to play. When the player begins to
read a CD, the Disc Check in Process message will
appear briefly to remind you of the delay. When the
map DVD is reinserted and read, the DVD Check
in Process message will appear briefly to remind you
of the delay.
While playing a CD in the CD player, the navigation
system is not available. A message will display
if the NAV key is pressed. If your vehicle is equipped
with Rear Seat Entertainment (RSE), you can play
an audio CD while using the navigation system.
