    Bose BT2-C5 Audio Streaming Module Instruction

    Bose-BT2-C5-Audio-Streaming-Module-Instruction productIntroduction

    The BT2-C5 module adds music streaming capabilities to C5 Theftlock CD or Tape radios (Bose and non-Bose). User has the option to install this module behind the radio cavity OR (if pre-wired), to the 10-pin CD plug in the trunk/hatch. Irrespective of install location, the BT2-C5 replaces the factory 12-disc changer (if present).

    If the vehicle has a CD changer and you wish to retain it, purchase our BTA-C5 instead. Alert: The BT2-C5 supports music streaming via Bluetooth, but does NOT support hands-free calls (HPF). Purchase our BT3-C5 for hands-free and music streaming. For more, see the frequently asked questions at the end of this guide.

    Safety Instructions

    • This installation guide is provided as a GENERAL installation guide; some vehicles vary, and
      may require additional steps.
    • We do not accept responsibility for third-party labour charges or modifications.
    • Exercise due diligence when installing this product.
    • We do not accept any responsibility for vehicle damage or personal injury.
    • Careless installation and operation can result in equipment damage

    Requirement

    • 1997-04 Corvette AM/FM/CD and AM/FM/TAPE RADIOS WITH AUX BUTTON

    Installing the Radio 

    Selecting the “install at radio” option means the module is to be connected to the 20-pin plug/connector behind the dash/radio. If the vehicle has a 12-disc CD changer in the trunk/hatch, it must be disconnected from the 10-pin plug in the trunk or hatch.

    Before getting started, we highly recommend disconnecting the negative battery terminal. If the vehicle has a 12-disc changer, please disconnect it from the 10-pin plug in the trunk/hatch

    1. Remove the radio from the dash to gain access to the factory plug
    2.  With the radio removed, release the 20-pin black/gray plug by pressing down on the black release tab.Bose-BT2-C5-Audio-Streaming-Module-Instruction fig 1
    3. Connect the 20-pin black/gray plug (from step 2) to the mating 20-pin socket (white) on the installation harness.Bose-BT2-C5-Audio-Streaming-Module-Instruction fig 2
    4. Connect the installation harness 20-pin black/gray plug to the radio 20-pin socket vacated in step 3Bose-BT2-C5-Audio-Streaming-Module-Instruction fig 3
    5. Connect the installation harness 16-pin plug to the module 16-pin connector. Alert: Ensure the 16-pin plug is fully seated and locked in placeBose-BT2-C5-Audio-Streaming-Module-Instruction fig 4

    Installation

    We highly recommend disconnecting the negative battery terminal

    1. Locate the factory 10-pin CD plug in the trunk or hatch area. If the vehicle has a 12-disc CD changer, it must be disconnected. To retain the CD changer, purchase our BTA-C5 instead.Bose-BT2-C5-Audio-Streaming-Module-Instruction fig 5
    2. Connect the factory 10-pin CD plug to the installation harness mating 10-pin socket (white).Bose-BT2-C5-Audio-Streaming-Module-Instruction fig 6
    3. 9Route the installation harness RED accessory wire to a 12V accessory (switched) supply in the vehicle. The 10-pin CD plug does not have a switched 12V wire. (Do not connect the red wire to the battery supply.)Bose-BT2-C5-Audio-Streaming-Module-Instruction fig 7
    Getting 12V switched power in the C5 Corvette

    We have 3 suggestions as to where to connect the installation harness red accessory (switched) wire:

    1. 1997-03 vehicles include a 3-pin plug under the passenger toe board/near BCM (may be covered in black duct tape). The yellow wire is ACC (Switched). If the vehicle does not have a 3-pin plug (e.g.2004), go to suggestions #2 &. #3 below.Bose-BT2-C5-Audio-Streaming-Module-Instruction fig 8
    2. Convertibles: It is also possible to get 12V “switched” power from the factory antenna wiring behind the passenger trunk area. Simply pull the carpet away and locate the 3-pin wire plug (orange, pink, black). The pink wire is switched and will power the module when the radio is turned on/off. Tap/splice the installation harness red wire to pink on the 3-pin plug.Bose-BT2-C5-Audio-Streaming-Module-Instruction fig 9
    3. Fuse #11, 22, 23 from the interior fuse box under the passenger toe board.Bose-BT2-C5-Audio-Streaming-Module-Instruction fig 10

    The mini-tap circuit is included for this purpose.

    Bose-BT2-C5-Audio-Streaming-Module-Instruction fig 11

    Wiring Instructions

    1. Strip 1/4- 3/8” insulation from accessory wire
    2. Insert the stripped wire into the blue butt connector
    3. Hold the wire in place and crimp (crimping tool, pliers, etc.) After crimping, verify crimp integrity by pulling on the wire.
    4. Go to the fuse box and remove factory fuse #11 or #22. If either fuse slot is empty has no fuse); skit to step 6. Insert the factory fuse into the empty slot on the add-a fuse tap
    5. Insert add-a-fuse blades into fuse box slot #11 or #22vacated in step 4. Alert: If the vehicle fuse slot #11, #22, etc. was empty, the empty fuse slot on the add-afuse circuit remains empty.
    Pairing

    Pairing process varies among devices, but the basic steps are the same. This process is done upon initial install and will not have to be repeated.

    1. Turn ignition and radio “O.N”
    2. From your Bluetooth-enabled device, turn the Bluetooth ON and search for Bluetooth devices.
    3.  When a list of available Bluetooth devices appears on your Bluetooth device, select “DisCarSt”.
    4.  Confirmation “tone” is heard on car speakers.
    5. The unit will automatically enter the BT Audio source, and you can now start streaming audio from your Bluetooth-enabled device. If the mobile phone doesn’t support the SSP (Simple Secure Pairing) Profile, please enter the pass code of “00.00.”

    1. Turn the ignition to “ACC”, turn the radio ON.
    2. Press the “TAPE/AUX” OR “CD/AUX” button on the radio to enter Bluetooth mode.Bose-BT2-C5-Audio-Streaming-Module-Instruction fig 13

    Troubleshooting

    Does the BT2-C5 require a 12-disc CD changer to work?

    • NO. If the vehicle has a 12-disc changer, it must be disconnected or purchase our BTA-C5 to retain it. I did not receive a microphone.

    Does the BLU-C5 not support Bluetooth hands-free calls?

    • NO; BT2-C5 module supports Bluetooth streaming only (A2DP). For Bluetooth hands-free purchase our BTH-C5CD or BT3-C5

    Can I install the BT2-C5 without removing the radio?

    • YES, but only if the vehicle has a 10-pin “CD” plug (See Fig. 6) in the trunk/hatch. To install BLU-C5 without removing the radio, select trunk/hatch install options from the drop-down. See question 6.

    Does installing the BT2-C5 disable the CD player built into the radio?

    • NO. The BT2-C5 adds music streaming to the existing system and does not interfere with the operation of the CD player built into the radio.

    Is it possible to install the BT2-C5 at the radio instead of the trunk/hatch?

    • YES; select “Installs at radio” from options in drop-down and follow installation 1 on page 2.

    How do I know if the vehicle has BOSE?

    • Check the speaker grills for the logo. See Fig.24

        I don’t think the title of your article matches the content lol. Just kidding, mainly because I had some doubts after reading the article.
