The TranzIt BLU HF App works in conjunction with the ISFM2351 hide-away Bluetooth audio module from iSimple, providing users a simple utility for managing their vehicle’s new integrated Bluetooth streaming audio and hands-free features, controlled via the stock steering wheel controls. TranzIt BLU HF goes far beyond other generic car Bluetooth kits by allowing users full control of their Bluetooth enabled smartphone or Tablet using their favorite Voice Recognition (VR) applications, all using the vehicle’s built-in steering wheel radio controls and their current FM radio. The TranzIt BLU HF App is used to remotely adjust certain, otherwise inaccessible, system settings, as well as providing users convenient access to the product’s user guide and other relevant online resources. From within the TranzIt BLU HF application, users are able to change the FM listening station from the default 98.1 MHz to any desired value between 88 MHz and 108 MHz. The TranzIt BLU HF App also allows operators to change the device name, adjust or reset the steering wheel control values, clear any previously paired Bluetooth devices, and even remotely update the hide-away module’s firmware.
