2. Manually tune through your local FM channels
Manually tune through your local FM channels on your vehicle's FM
radio. Turn on your vehicle's FM radio. Start at 88.1 and use the 'Manual'
tune function on your vehicle's FM radio to tune through each FM
channel one-by-one (88.1 followed by 88.3 etc.) to locate channels that
aren't being used by a local FM radio station. Write down each FM
channel that has only static or silence on it, until you reach 107.9. Once
you have created your list of available FM channels, you will need to find
the one that provides the best match for Onyx EZ.
Tune Onyx EZ to a favorite XM channel (or to channel 1, if it's not
activated). Pick the first FM channel on your list and tune the FM radio to
that channel. Then tune Onyx EZ to the same FM channel. (Refer to "Set
and Select an FM Channel" on page 63.) You should hear the XM
channel through your vehicle's radio. If you are satisfied with the sound
quality, you're done! If this FM channel doesn't work well for you, work
down the list until you find an FM channel that allows you to hear XM
clearly.
NOTE! You may find an FM channel with static or silence that does not work
with Onyx EZ. It is possible that some type of inaudible interference is
present that prevents reception of the XM broadcast. Your only options are to
use another FM channel or a different audio connection method.
TIP! If you regularly drive from one location to another, such as your daily
commute, you may need to use different FM channels along your route for
best performance. If this is the case, we recommend saving the best FM
channels as presets on your FM radio and Onyx EZ. Then you simply select
and match the best channel for the area you are in.
TIP! It will be much more difficult to find available FM channels in large cities
than in most suburban or rural locations. A direct audio connection using the
Aux In Cable, Cassette Adapter, or professional installation is your best
