Installing the Handsfree Kit
User Interface Module
The User Interface Module (UIM) cable can be mounted in 
several ways to provide a safe and comfortable 
environment for use.
Audio Connections
You can install the system’s audio components in one of 
2ways:
External Speaker
If you are installing the system with the external speaker, 
you MUST leave the audio output (+/-) lines disconnected. 
(See “Power Connections” on page 45.) The external 
speaker should be connected to the interface cable.
Vehicle Radio
If you intend to connect the system to the vehicle radio to 
control audio level and the radio supports it, you must 
connect the audio output (+/-) lines to your vehicle’s 
entertainment system.
Note: 
The system's handsfree audio has been optimized 
for the external speaker.  Routing the audio output through 
the vehicle's entertainment system may alter the 
handsfree audio performance.
Installing the Electronic Module
The best location for the electronic module is under the 
vehicle’s dash. The box must be protected from dirt and 
moisture and have adequate space for cooling and to allow 
for cable connection.
