Pontiac 2004 Bonneville - Manual (Page 221)

Trunk-Mounted CD Changer
With the optional CD changer, you can play up to
12 CDs continuously. Normal size CDs may be played
using the trays supplied in the magazine.
The small CDs (8 cm) can be played only with specially
designed trays.
Notice: Placing heavy objects, which may shift or
slide while driving, in the trunk could damage
the CD changer. If your vehicle has the optional CD
changer, do not put heavy objects in the trunk.
You must first load the magazine with CDs before you
can play a CD. Each of the 12 trays holds one CD. Slide
the button on the top of the magazine and pull gently
on one of the trays. Load the trays from top to bottom,
placing a CD on the tray label side up. If you load a
CD label side down, the CD will not play and an error
will occur. Gently push the tray back into the magazine
slot until it locks into place. Repeat this procedure
for loading up to 12 CDs in the magazine.
