The system uses a wireless FM Transmitter (FMT) to send audio 

through the vehicle’s speakers. To listen over your speakers:
1  Make sure system 

MUTE is off. Press SPEAKER.  “SPEAKER 

SOUND ON FM _ _ . _”  appears. Select a FM frequency as de-

scribed below.

2  Turn on the car radio.  Tune to the FM frequency displayed on the 

screen, such as “FM 88.1.” 

3  If no system audio is heard, try changing the FMT frequency and 

re-tuning the radio to the new frequency. 

  Press 

SPEAKER. “Speaker Sound on FM _ _ . _” will be displayed.

  Now use the 

LEFT and RIGHT buttons to change the frequency. 

Select a frequency, re-tune your radio and check for clear sound. 

The system saves the frequency you select, and returns to it each time 

the system is turned on. You may want to store the FMT frequency as 

a preset of your radio for ease of use.

If the words “HEADPHONES ONLY” appear, the internal FMT is 

turned off. It can be turned on by pressing the SPEAKER button and 

selecting a FM frequency. If the words “SPEAKER SOUND” appear, 

an external FM Modulator (FMM) is probably being used. In this case, 

the 

SPEAKER button turns the external FMM on and off.  The Rosen 

external FMM frequencies are FM 87.7, 87.9, 88.1, 88.3, 88.5, 88.7, 

88.9. If you have any questions about your FMM,  please contact your 

Rosen dealer.

When you insert an audio CD (label facing away from you), the 

standard CD commands (PLAY, NEXT, etc.) will control the unit. Some 
CDs recorded in CD-R or CD-RW mode may not play.

When a disc containing MP3, JPEG or MPEG files is inserted, a menu 

screen appears. Use the arrow buttons to select a file type and press 

enter to play it.

Inserting a USB drive into the available connector will cause DVD play-

back to stop and open a directory of the USB drive contents.

This may take several minutes depending on the amount of data.  Use 

the arrow buttons to select a file type and press enter to play it.
