Module, Hands Free (HFM): Description
The Hands Free Module (HFM) (1) is found in vehicles equipped with the optional Uconnect® Hands Free Communication System. This module is located on the inboard side of the instrument panel support structure end bracket outboard of the glove box opening. The HFM hardware and circuitry is contained and protected within a molded black plastic housing that has two integral mounts (4). The HFM is positioned to the die cast end bracket, then secured to the bracket by two screws.
The HFM has three integral connector receptacles that are oriented toward the dash panel when it is installed in the vehicle. The two largest receptacles (2) connect the HFM to the vehicle electrical system through dedicated take outs and connectors of the instrument panel wire harness. The smallest connector (3) accepts a Universal Serial Bus (USB) cable connector that connects the HFM to the Radio Receiver Module (RRM).
The internal circuitry of the HFM includes a microcontroller, flash memory and a Bluetooth™ module. The module also includes sophisticated Voice Recognition (VR) software. The HFM software is flash programmable.
The HFM cannot be adjusted or repaired and, if damaged or ineffective, the entire HFM must be replaced.
