Introduction: Safety comes first when you re on the road, so having an intuitive and easy to use Bluetooth kit is essential to reducing driver distraction. The MBCD-HF kit is compatible with virtually all Bluetooth phones, and sounds great whether for mobile conversations, streaming music or listening to the CD Changer. In addition, a USB Charging port is included to keep audio devices fully charged. One button with built-in microphone conveniently installed on the dash is used to launch Voice Recognition (Siri, Google Now, Assistant etc.), initiate phone calls, launch applications and switching on the CD Changer. Thanks to the MBCD-HF Kit you can keep the radio, CD Changer and vehicle you love while enjoying Bluetooth features only available on newer cars. Notes: 1. A working CD Changer must be present otherwise this kit will not apply. 2. 2, 1999+ vehicles are not compatible. Fig. 2 Mercedes Radio 2.

Consider where to install control/microphone button. Keep in mind the control button must be within reach and facing driver for voice commands and phone dialog (cable is 6ft. long). We recommend completing the rest of the install prior to securing control/mic button. Once you decide on a location simply remove tape backing from control /mic button and stick to surface.

Bluetooth Module also includes a USB Charging port. Should you decide to use it, we suggest one of 3 connecting options: A. Flush to dash/panel requires drilling a ¾ hole in the dash B. Flush with Support bracket (use this option to mount USB terminal wherever your installation demands without drilling) C. No USB Mount- (default) 3. Push USB head (See Fig. 15) until it snaps in place and flush with mounting surface (See Fig. 16) A. Flush to Dash or Panel (req. drilling) 1. Drill a ¾ hole in dash or panel using a step drill bit or equivalent (See Fig. 13) Fig. 15 Flush mount USB Terminal Fig. 13 Step drill bit 2. Insert 3ft. USB cable (See Fig. 14) through ¾ hole created in step 1 Fig. 16 Flush mounted to dash 4. Connect USB male terminal (See Fig. 14) to USB port on Module (See Fig. 17) Fig. 14 3 ft. USB cable Fig. 17 Module USB Port 5. Tuck and secure any extra wire from moving parts and proceed to test operation (Proceed to Bluetooth Pairing and connection)
B. USB Bracket Mount (No drilling) 1. Locate a flat surface at location of choice within 3.2 ft. of radio to mount USB bracket (See Fig. 18) to surface using adhesive/tape or screws (included) Fig. 18 USB mounting bracket 2. Insert USB male terminal through hole in bracket (See Fig. 19) 5. Tuck and secure any extra wire away from moving parts and test operation (Proceed to Bluetooth Pairing and connection) C. No Mount USB port on module is for charging only. Use your own USB extension cable option or proceed to next step if charging is not required. The radio cavity in most vehicles lack extra room needed to fit aftermarket equipment and because of that you will have to be creative when fitting these parts. Extra length cables are provided to allow for flexibility. Bluetooth Pairing and Connection This process is required the first time you use the MBCD-HF. After initial pairing, the MBCD-HF will automatically reconnect with paired phone upon entering vehicle. Fig. 19 3. Push USB head until it snaps in place and flush (See Fig. 20) 1.
