using car stereo or steering wheel controls, speak to the other person using microphone provided with GROM Bluetooth

1.6 Precautions
Proper mounting location securely installs the interface in a location free from heat, humidity, moving parts, or direct sunlight.
Beware of hot-air flow from your vehicle’s climate control system. The interface should be secured in a suitable location, free of
sharp metal edges, using double-sided tape, Velcro, or wire ties. The adapter’s operating temperature range is -30°C to +70°C (-
24°F to +158°F)

- GROM Audio has confirmed the listed stereo and vehicle application to the best of our ability. Due to uncontrollable factors and

1.9 Important Compatibility Notes
- If your vehicle is equipped with an external factory CD changer, you must disconnect it in order to be able to install the
GROM interface. You will lose the use of the external CD changer to gain the use of your iPod, iPhone, Android, Bluetooth
or MP3 player. The built-in CD changer will remain operational. SAT if present may need to be disconnected in some case.
- If your vehicle has factory SAT and GROM adapter is using SAT emulation, you must disconnect factory SAT to gain the
use of your device, iPod, Bluetooth or MP3 player. This is applicable to Nissan/Infinity with SAT emulation, Honda/Acura 03
and up with SAT emulation, Ford/Lincoln/Mercury, Mazda 3,5 08-09 and Subaru 07-09. For a full version of the GROM
compatibility guide, please visit http://gromaudio.com/grom_application_guide.pdf or contact GROM Audio at

1.10 USB/EXT1/EXT2 ports
It is recommended for you to use GROM automotive grade USB extension cable. It will ensure better connection using the latch
system that withstands the moving vehicle conditions. In addition it will prevent the wear-out of USB port on GROM-IPD4 adapter.
Please refer to the Figure below for the proper connection of the accessories to the EXT1/EXT2 ports on GROM-IPD4 module.

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.
