Chapter 2 – General Installation
2.1 Installation location
Most installations will require removing the factory stereo in order to plug in the vehicle- specific harness. For some
vehicles, you will also have the option to connect the interface to the factory pre-run CD changer cable located in the
trunk or glove box.
2.2 Tools needed
In most cases, there are no special tools required in order to remove the stereo. For some stereos (e.g., VW, Audi), it
is better to use car stereo removal tools. Please consult your local car audio shop or your vehicle’s dealership for
instructions or assistance as necessary. If you are unsure how to install the interface properly, we recommend
contacting your local car stereo shop for assistance. Some installation examples can be found at
www.gromaudio.com.
2.3 Preparation and adapter installation
1. Turn off car engine and remove key from ignition
2. If your stereo uses a Security Code, make sure that you have the code before unplugging the stereo.
3. Remove your stereo from the dash in order to gain access to the back of the stereo. Some vehicles require special
tools to remove the stereo. Please consult your vehicle’s dealership or a local car audio professional, if necessary.
4. Attach the car harness connector to the CD changer port in the back of the stereo. Be sure to make a secure
connection with no bent pins, but do not force it. Connect the other end to the interface.
For VW/Audi/Seat/Skoda with dashboard cable only:
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 GROM 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
