There is a black single cable on the vehicle-specific harness (Figure 5) that you will need to attach to the
back bolt of the car stereo or the stereo chassis stereo.
Remove the PVC from the end of the black wire (2)
• Connect the end of the black wire (2) to the metal part of the car stereo chassis. You can connect it
under the bolt (3) if it is present
• Make sure that solid contact is made between the striped black wire and the metal part of the car
stereo body.
• Note: Failure to attach the black cable to the chassis of the stereo will result in the NEO adapter not
working! All of the specified vehicles require this black cable to be attached.
5. For Audi vehicles only: Some Audi head units require an additional part (AUDS cable) or harness
modification to gain the access to the CD changer port. A solid 20-pin connector occupies the 8-pin CD
changer port on such stereos.
6. For BMW behind the stereo, Ford, Nissan, Infiniti, Volvo, Mazda 08-12, Mitsubishi vehicles only:
Please refer to the installation insert for the special guidelines for BMW, Ford, Nissan, Volvo and Mazda
installation.
7. For Toyota and Honda (03 and up) vehicles:
On some Toyota/Lexus/Scion vehicles and Honda/Acura (03 and up) vehicles, the CD changer port is
occupied by a factory harness (such as NAV or audio harness). The NEO package for Toyota and for
Honda/Acura (HON1) includes a Y shaped vehicle cable. In order to connect the interface properly,
please refer to Figure 6. If stereo port is already empty, simply plug NEO cable into stereo.
8. Turn your car stereo on and switch it over to CD Changer mode using the Disc/Mode/CD/AUX buttons
on your car stereo (depending on the stereo type). You may have to press CD/Disc twice to access CD
Changer mode. Your display should now show Disc 1, Track 01 or similar.
9. Connect the USB cable to the USB device. Turn on your car stereo and play some music from your USB
device (folders need to be setup). You should hear the sound coming from the car stereo speakers.
10. Once you confirmed the operation of the interface, continue with the installation. If you have
trouble with the installation, please see our troubleshooting section.
