Factory Stereo Replacement Interface With Chime (Class II Data System) PDF Manual

There are 2 types of Bose systems available in some models of vehicles listed above. Turn factory radio volume up and down rapidly. If the sound system reacts immediately then the system is a standard BOSE, not a Premium BOSE. If the sound system volume does not react immediately, but has a noticeable delay, the system is a Premium BOSE and not compatible with the GM09SR. If “Premium” Bose Amplifier is not used or is bypassed, then the GM09SR can be used to retain warning chimes only. Alternate parts are available to INTEGRATE “Premium Bose” and OnStar systems.
Your Factory stereo is an integral part of your vehicle’s SAFETY and WARNING CHIME systems. If the stereo is removed without the proper installation accessory, various warning chimes and/or some functions of your vehicle may be LOST including:
• Key left in ignition chime
• Seatbelt warning chime
• +12V Accessory Power at Radio’s location
• Lights left on chime
• RAP (Retained Accessory Power)
• Low fuel
• Check Engine/Service indicator
• Low oil level

Your vehicle’s ECM (Electronics Control Module) will also store an error code if operated without the factory radio installed and you may experience difficulty in having the vehicle serviced at the dealership. The GM09SR Interface module / harness allows you to REPLACE the factory stereo and RETAIN all SAFETY and WARNING chimes. Additionally, GM09SR will send the proper data commands to your vehicle’s ECM (Electronics Control Module) to indicate a “Healthy” status for diagnostic purposes. The GM09SR Module/Harness ALSO provides a RED +12V Switched ACCESSORY Power source for your aftermarket stereo.

WIRING INSTRUCTIONS
1. Disconnect the Negative battery cable from the battery to avoid any short circuits.
2. Remove and unplug factory stereo. (If needed, call Scosche Tech Support (800) 621- 3695 x3 for stereo removal steps specific to your vehicle.)
3. Match and connect the appropriate wires from the GM09SR harness to the appropriate wires of the plug provided with your stereo. For example, connect the +12V Yellow Constant lead from your stereo to the Yellow wire of the GM09SR Harness. The color codes are designed to match MOST brand of car stereos.
A. For NON-Bose installations, cut off RCA cable ends and connect direclty to color coded speaker wires. For STD BOSE systems, USE RCA line outputs from stereo.
4. Note that the RED +12V switched wire for your aftermarket is coming from the GM09SR module itself, not the vehicle harness.
5. Tape all unused wires to prevent short circuiting.
6. Reconnect the Negative battery cable
7. Connect the 16-Pin harness to the GM09SR module.
8. Connect the 24-Pin GM09SR connector to the Factory Harness.
9. As you install your new stereo, place the GM09SR module in the rear of the dash cavity behind the stereo. (Optional: Cable ties or double sided tape can be used to secure the module, but are not included.)

WIRING NOTES:
1. The Red +12V Accessory wire coming from the GM09SR module is rated at 5 Amps Max for a SINGLE Aftermarket Car Stereo only. Connecting additional accessories to the RED wire can cause DAMAGE to the GM09SR module!
2. There additional Yellow, Black and Violet wires PRE-CONNECTED between the GM09SR connector and the Vehicle 24 PIN connector. These are Power and Data wires for the module itself. DO NOT MAKE ANY CONNECTIONS with these wires.
3. If your stereo does not contain an “illumination” wire, then the Orange wire will not be used. Tape or terminate all unused wires to prevent short circuits.

CHIME AUDIO LEVEL ADJUSTMENT
The GM09SR interface gives you the ability to adjust the chime audio level from soft to loud in order to suit your personal needs. Follow the steps below:
1. With the Ignition key OFF and Key resting in ignition, turn ON Vehicle headlights.
2. Open driver’s door. At this point you will hear a reminder chime indicating the Key is in the ignition and lights are on.
3. SLOWLY, rotate the dash illumination dimmer knob to make chime audio adjustments. Turn the knob up to increase chime volume level or turn it down to decrease.
4. Once the desired volume level is achieved, turn off headlights and close the door. Your personal chime setting will be stored by the GM09SR. You can re-adjust your dash lighting dimmer level with the door CLOSED and headlights on.

OPERATION
There are no specific “user operational steps for this product other than CHIME ADJUSMTENT as stated ABOVE. When connected and installed per these instructions, your Aftermarket Car Stereo should operate just like the Factory System did. All Chimes will be re-produced by the speaker built inside the GM09SR located in the dash behind your stereo. The Retained Accessory Power function of the stereo will continue to operate as normal. The GM09SR module will send the proper DATA commands to your vehicle’s Electronics Module to keep your vehicle’s Diagnostics System functioning normally as with the Factory Stereo. Consult your Stereo Owner’s Guide for info specific to the operations of your new Car Stereo.
