VOICE ACTIVATED CELLULAR TELEPHONE/CD CHANGER INSTALLATION
Application Specific D2B Notes:
•CD changer, telephone, and voice recognition module fibers are installed at the factory. Telephone and
voice recognition fibers run along the left rear quarter panel and the CD fibers along the right rear quarter panel.
•The vehicle is configured from the factory for the CD changer only.
•Two sets of fiber cables run along the left quarter panel. One set is for the telephone only and the other for
telephone and voice recognition. While not in the factory configured ring, these optics are coupled together
just forward of the battery on the right. Which set of optics to use, will depend whether the telephone only or
telephone with voice recognition will be installed.
•All reconfiguration points are in the trunk in front of the battery and to the right of the fuse panel.
WARNING!
Disconnecting the negative battery cable is not recommended due to otherwise extensive
reprogramming requirements. WIRING HARNESSES WILL BE ELECTRICALLY ACTIVE. IT IS
THEREFORE NECESSARY TO EXERCISE EXTREME CAUTION WHILE EXECUTING THESE
INSTALLATION INSTRUCTIONS. FAILURE TO DO SO, COULD RESULT IN SEVERE PERSONAL
INJURY OR DEATH FROM ELECTRICAL SHOCK. The ignition and radio power must remain OFF until
the final test is performed.
