BT45-INFI Package Content
• 1 Owner’s Manual • BT-INFI Cable
• 1 BT45 Interface Module • 1 Microphone
Introduction
The BT45 seamlessly integrates your vehicle’s OEM sound system with
Bluetooth (HFP) devices so you can make hands free phone calls and
stream your music. You can wirelessly connect your A2DP Bluetooth
prole equipped smartphone or tablet to playback stored music or stream
from your favorite music apps such as Pandora or iHeart Radio. The
BT45 also includes a 3.5mm auxiliary audio input so you can play back
music stored in your non-Bluetooth devices.
The BT45’s plug & play technology takes advantage of the OEM radio’s
ability to accept an external CD changer or Satellite Radio by converting
it into Bluetooth phone/audio streaming/AUX input source. This design
innovation allows you to maintain functionality of any of the following
existing factory installed options: Bluetooth HandsFreeLink, LiveTrafc,
Navigation, CD changer, Satellite radio, RSE (rear seat entertainment
system), and AUX/USB input.
