Delta fixed coded radio

Overview

As of model year 1990, Delta radios are assigned a fixed four digit security code from the factory. Unlike previous coded radios, the security code cannot be changed.

The fixed coded radios have been implemented gradually and can be identified by the part number. A part number label is attached to the radio chassis.

Delta — Part No. 893 035 093B
Delta Bose Part No. 893 035 093C

CAUTION
Part numbers are for reference Only.
Always check with your Parts
Department for latest information.

The radios are not coded at the factory. To activate the theft protection, the radio must be coded during the Pre-Delivery Inspection.
The security code and serial number of the radio are printed on a removable sticker located in the trunk near the vehicle identification sticker.

CAUTION

DO NOT keep the security code or radio
card with the vehicle. Always instruct
customers to detach radio card from
