1. Introduction
Thank you for choosing the iSimple ISFM22 as your audio input solution. The ISFM22 (TranzIt
BLU) is designed to provide the connecting link between your iPod or iPhone, and your vehicle.
This interface provides a Bluetooth connection point for your iPod or iPhone, and delivers
streaming audio directly into your radio.
2. ISFM22 Components
• Radio input module
• Application (Free download from the app store)
3. Installation Options
(Choose A or B)
The ISFM22 interrupts the incoming antenna signal when in use, to deliver the cleanest
audio possible from your device. To regain standard FM operation without interruption,
simply pause the iPod or iPhone, and approximately 8 seconds later the full FM band will be
accessible. There is also a power on/off/auto option in the TranzIt BLU app. If manual power
on/off control of the ISFM22 is desired, disconnect the “loop plug”, and plug the “optional
toggle switch” into the power harness, in its place. This will allow the user to turn the ISFM22
on or off at any time.
