AC504BiM OPERATION
The AC504BiM supports A2DP (advanced audio distribution profile) wireless streaming
audio from your Bluetooth mobile device directly to your head unit. You can also control
your music from the front panel of the head unit using AVRCP (audio video remote control
profile).
Notes:
• To stream music to your head unit, your mobile device must support the A2DP and
AVRCP Bluetooth profiles. Check the owner's manual of your mobile device for details.
• Streaming audio must be enabled from your mobile device. This option will vary
depending on the device. Some devices allow streaming audio to be disabled.
After pairing, connecting and enabling streaming audio from a compatible mobile device,
begin playing music using the music player on your mobile device. Once the music is
playing, the following functions can be used to control the music:
• The
ll
button will skip to the next available audio track.
• The
nn
button will skip to the previous audio track.
• The
l
/
II
