Modes and Control Button Operation
In order to stream your music through the vehicle, you must first engage the
ISFM2351 for music streaming. To do this, simply press and hold the control button
for more than 4 seconds. A series of beeps will play through the FM frequency, or Aux
source. Now begin playback on your smartphone by tapping the control button if a
music app is already running, otherwise, launch your music app and press play on the
app and the audio will play through the vehicle.
If you would like to listen to the regular FM station, simply disengage the ISFM2351
by pressing and holding the control button for more than 4 seconds. Note, when
“disengaged” the ISFM2351 is still connected to your Bluetooth device for hands free
calling.
