Thank you for purchasing the GROM-USB2 adapter, which has been designed to
provide endless hours of listening pleasure through most vehicles' factory radio. To
ensure that your GROM-USB2 interface performs correctly in your car or truck, we
recommend that you read this entire manual before attempting to install the GROM
interface.
1.2 Functionality highlights
The GROM-USB2 car adapter allows you to easily access your media collection in your
car, including shuffling songs, skipping between tracks, and adjusting the volume—all
with only your factory car stereo head unit or multifunction steering wheel controls. This
adapter further allows you to listen to your favorite music directly from any mass storage
USB stick or hard drive, requiring no dedicated portable player. GROM-USB2 also has
additional AUX and iPod inputs, allowing you to connect any additional audio source and
iPod / iPhone.
1.3 Main Features
- Ability to manage a significant number of songs based on the memory of the USB
disk/flash stick
- Folders or Playlists on the USB drive are mapped to an individual "Disk" button on car
stereo's dashboard
- Number of "disks" limited to the car stereo (up to 99 on select stereos)
- Last listened song position within the playlist is remembered
- Last listened song time position is restored upon ignition cycle
1.4 Precautions
Proper mounting location
Securely install 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)

The GROM itself will enumerate subdirectories and turn them into a flat list of tracks. - If filenames in a certain directory begin with digits, they will be played in ascending order based on the order of those digits in the filenames.
