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 extension port in the back of the stereo (most setups).
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 (ground) 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
Figure6. VW /Audi / Seat/ Skoda Connection Scheme
Remove the PVC from the end of the black wire (2)
(a)
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
(b)
Make sure that solid contact is made between the stripped black wire and the metal part of the car stereo
body.
Note:
Failure to attach the black cable to the chassis of the stereo or ground will result in the GROM adapter not
working!
All of the specified vehicles require this black ground cable to be attached.

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. Please refer to the instructions at
http://gromaudio.com/docs/grom-audi-how-to.html
for more information (AUDS cable is highly recommended in this case).

For BMW dashboard, Ford/Lincoln/Mercury, Nissan/Infiniti, Volvo, Mazda 3, 5, CX-7 08-12 vehicles
only:
Please refer to the installation insert for the special guidelines for installation using P-Tap locks.

.
For Toyota/Lexus 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 GROM 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 7
.
If stereo port is already empty, simply plug
Grom cable into stereo
. You do not need anything connected to the female Grom harness. It is optional.
