Here's a great way to add SIRIUS Satellite Radio to your vehicle without replacing your factory radio. Connect your Kenwood SIRIUS tuner to the KCA-R70FM FM modulator/controller, tune to an unused FM frequency, and prepare to be entertained by 100 channels of Sirius programming! Select from 12 FM frequencies for the best possible reception in your area. It's a great option for drivers of classic cars, people who lease their vehicles, and anyone else who wants to keep the "factory" cosmetics of their dash.

The package includes an FM modulator (converts the signal from Kenwood's SIRIUS Satellite Radio tuner into an FM signal), a wired display/control panel, and a convenient wireless remote. Mount the wired display near your radio for easy operation and control — SIRIUS channel name and number, artist, or song title are displayed in a scrolling text format across the backlit screen.

The modulator has a 13-pin input that also accepts the cable from a Kenwood CD changer or digital media player. Or you can connect the Music Keg or CD changer to the pass-through input on the SIRIUS tuner, and use the source selector on the KCA-R70FM's display panel to switch between the two. The display allows you to navigate through MP3 files and folders, access repeat, scan, or random play modes, and read ID3 tag information (artist, album, song title).

Adjust the volume of the playback to match your radio with the modulation level control, or use Dynamic Control to boost high frequencies for extra clarity. In addition to the wired control/display panel, you get a handy 10-key wireless remote.

FM Modulator Features
Display/Controller Features

Overview: This FM modulator/controller allows you to add a Kenwood Sirius Satellite Radio tuner to your vehicle's existing radio in order to receive Sirius Satellite Radio broadcasts. Alternatively, you can connect a Kenwood CD changer or Music Keg digital media player to this unit.  If using the Kenwood KTC-SR901 Sirius Satellite Radio tuner, you can use the pass-through input on the tuner to connect the changer or Music Keg, and then switch between the two sources with this FM modulator/controller. Note: The Kenwood KCA-S210A adapter is required if connecting a Kenwood disc changer released in 1997 or earlier (a disc changer not equipped with the "O-N" switch).

FM Modulator Features

12 Modulation Frequencies: The output can be modulated on one of 12 different frequencies. They range from 87.7 MHz to 89.9 MHz in 200kHz steps (87.7, 87.9, 88.1, 88.3, 88.5, 88.7, 88.9, 89.1, 89.3, 89.5, 89.7, and 89.9).

4 Step Modulation Level: This feature lets the user adjust the output level of the modulator to best match the radio's input, which reduces distortion when playing CDs.

Dynamic Control: This feature automatically controls the level and separation of the FM modulator output to better match the FM radio's input. This reduces noises and distortion when playing CDs.

Text Scroll: This display/controller allows you to scroll through various text information automatically. However, this feature can be turned off to allow you to manually scroll through text data.

Display/Controller Features

Sirius Satellite Radio Control Features: When a Sirius Satellite Radio tuner is connected, this unit will display various types of text data including Sirius channel name and number, song title, artists name, category name, and album title.

  • Preset seek tuning

CD Changer Control Features: In addition to displaying disc and track title, disc and track number, track time, MP3 file and folder number (requires a Kenwood CD/MP3 changer), and CD Text information, the following control features are available when a Kenwood compatible CD changer is connected:

  • Audible fast-forward/fast-reverse
  • Intro scan
  • Random (disc, MP3 folder, all discs)
  • Repeat (track, disc)
