• The car kit is intended for use in 12 Volt negative
ground systems only. The car kit draws less than 3
Amps. Confirm that the vehicle's electrical system can
supply this current.
• The installation steps are in no particular order. In
general, you should first pick the locations where you
will be mounting the UIM, microphone, speaker, and
ECU. Mount the UIM, speaker and microphone and
route the cables to the ECU mounting location. Install
the power adaptor cable. Plug everything into the ECU,
and then mount the ECU.
• The car kit has separate output paths for the handsfree
audio (line and speaker levels) and music (RCA
line-level output). Both handsfree and music audio
paths need to be connected for full system operation.
