Generally, there are two ways to install the Gateway:
- If the car does not have a CD changer: you install the Gateway as last device in the optical ring of the car. In other words: you install the Gateway behind the head unit of the car. (You can follow the small arrows on the optical connectors that show you the direction of the optical light.)
- If the car has a CD changer: then you first remove the CD changer from the optical ring and install the Gateway to the disconnected optical cable of the CD changer.
When the CD changer connection is located in the boot of the car, then you might need the FOA1PO1 optical extension kit, if you want/need to place the Gateway hardware to the front part of the car (into the glove box or behind the dash).
Other special case:
- Porsche: Alternatively, if the phone module is under the passenger’s seat and it is not needed, then you can install the Gateway device there, and then no optical extension kit (FOA1PO1) is needed. So first remove the factory phone module and install the Gateway to the disconnected optical cable of the phone module. Finally remove the CD changer from the optical ring, then you need to make an optical loop on the disconnected CD changer cable.
