Introduction
If your 1st Generation CTS or SRX has an XM tuner module (with or without
subscription), you should consider adding the CTS-HF module for Hands-free
calls, music streaming, charging and more. From push-to talk button (with built-
in microphone) conveniently installed on the dash, users may launch voice
recognition application (Siri, Google Now, Assistant etc.) initiate phone calls,
launch applications or XM playback (if subscribed). Thanks to the CTS-HF Kit, the
original radio, XM subscription is retained in addition to Bluetooth features
only available on newer cars.
Warning: XM Subscription not require; however, if subscribed that option remains
active. An aux input jack is provided for non-subscribers. (Subscribers are exempt
from the aux input jack)

15. Consider where to install push button/microphone. Keep in mind the
control button must be within drivers reach and facing for voice
commands and phone dialog (cable is 6ft. long). We recommend
completing the rest of the install prior to securing the
control/mic button to the dash. Once you decide on a location simply
remove tape backing from control /mic button
Make sure no ventilation duct is pointed towards the mic.
It is best to mount button facing driver
The Bluetooth module includes a USB charging port. An optional USB extension
cable kit is available. Should you decide to purchase/install, we suggest one of 2

wherever your installation demands without drilling)
A. Flush to Dash or Panel (drilling required)

Frequent ask questions & troubleshooting
1. My vehicle has XM Tuner module but subscription has expired. Will the
CTS-HF work without subscription?
YES. In addition, an AUX input is provided by which users can connect and
play auxiliary audio devices (Mp3 Players, iPod, DVD, iPad etc. Auxiliary
input is not available to XM Subscribers.
2. I’m not the original owner and don’t know if vehicle has XM Tuner. How
can I find out without ripping it apart?
Turn Radio “ON”. Press “BAND” button repeatedly to cycle through
AM/FM/CD/XM1/XM2. If only AM/FM is displayed, vehicle does not have the
XM Tuner Module and not compatible.
3. Does the CTS-HF work on all radios?
Works CTS Navigation and non-Navigation radios and non-Navigation SRX.
Does not work on SRX Navigation radios.
4. Can I control my Smartphone music from the radio buttons?
NO; you must continue to use Phone built-in controls or the Bluetooth
control button and/or voice commands to operate the device. Factory
radio volume button is used to set playback level.
5. Does the radio screen display phone number and song name?
NO. Smartphone screen must be used to display song and number details.
6. How to I listed to XM?
Press BAND or XM button on radio to enter XM mode (if not already) then
press control button 4 times. These steps also apply to play Auxiliary
device (non-subscribers only)
7. Where is the best place to install the control button/mic?
We found that having the control button/mic mounted higher on the dash
worked best, but users can experiment with different location and decide
which works best for them.
8. Will the radio mute when I receive or make a phone call?
This system will not mute audio playback unless radio is in Bluetooth mode.
If listening to AM/FM, the radio will not mute. In addition, radio must be
switched to “XM” (Bluetooth Mode) so caller can be heard on car speakers.
9. My second phone does not pair or find the Bluetooth module?
In order to pair another phone make sure no other phones are connected.
Once Bluetooth is turned off, the device will be free and ready for pairing.
10. Will I be able to use the USB port to connect and play music from flash
drives?
NO. The USB port is for charging only (1.8A). Devices requiring more
charging current will not charge from this module.
