| This module comes with our USB Field Upgrade and Configuration Port! We recommend connecting it to a computer BEFORE YOU INSTALL and using our support app "m4cconnect" to do a quick firmware update check. M4cconnect as well as all other information regarding USB update and configuration can be found at www.mods4cars.com/usb. You can even configure and activate your favorite module functions and settings on screen before the module is installed in the car! It is a good idea to permanently install the USB cable with the module in the car, leaving the computer plug in an easily accessible spot for later use with a Wifi/3G/4G connected laptop. |
| IMPORTANT TROUBLESHOOTING TIPS If the top does not work properly or at all after installing the module, these tips can be very helpful: • 1) Turn Function 1 (Main Switch) off (Setting 0). The module will be completely passive. If the problem still persists and the top won't work, check all connections. Please also check the green DATA LED on the module! • 2) Function 2 now has a valet mode (Setting 2) on many modules. Valet mode completely disables opening of the top. Check the setting for function 2 and make sure the module is NOT in valet mode! IMPORTANT: Not all modules have the valet mode! Please check the Operation and Programming Manual! |
| FUNCTION OF THE DATA LED The DATA LED shows the module status and helps troubleshooting issues during installation: • When the ignition is ON: The LED should BLINK (flash) in a regular pattern (about 1x per second). This indicates that the module is receiving data and should work OK. • When the ignition is OFF: The LED should BLINK (flash) as long as the data bus is still active and turn off after a while (max 5 min) indicating that the car has entered stand-by (sleep) mode. • If the LED is permanently lit with the ignition ON, the module is NOT receiving data from the top controller and all connectors should be checked. • If the LED does NOT light up at all when turning the ignition ON, the module is either not getting power or not receiving ANY data. All connectors should be checked. |

| USE OF THE 3M WIRE TAPS This module is installed using the 3M wire taps very popular with 12V aftermarket industry for their reliability and durability. The most common problem during installation is a bad contact between the plugs from the supply wires and the wire taps. Please make absolutely sure that the metal blades of the plugs slide into the slots of the t-taps. It happens that the blade "misses" the slot and the connection looks correct, but doesn't make electrical contact! The T-taps come in RED (for thin wires), BLUE (for medium wires) and YELLOW (for thick wires). To test if you installed the module correctly after all wires are connected, turn the ignition fully on and watch the green LED on the module. It should blink (flash) to signal a correct installation. If the LED either does not turn on or stays on permanently, there is a bad contact or a missing connection! See detailed explanation of the DATA LED. |
| USE OF TYCO AUTOMOTIVE CONNECTORS THE PHOTO IS A SAMPLE AND ONLY SHOWS WHERE TO FIND THE NUMBERS AND HOW TO INSERT THE PINS. SOME CARS REQUIRE THE RED AND BLACK WIRES REVERSED! PLEASE FOLLOW THE BELOW STEPS FOR CORRECT WIRE ASSIGNMENTS!!! The wiring kit for this module uses one or more of the TYCO connectors shown on the left. These are specialty automotive connectors designed for tight and secure electrical connections. In order to avoid reversing polarity, please pay attention to the small numbers embossed in the back of the plugs where the contacts are inserted. In case one of these plugs will need to be removed later, it can be done without any damage to the plastic cap or the crimp contacts. Please see our Knowledge Base article(s) regarding these plugs at http://mods4cars.com/support/knowledgebase.php?search=tyco. |
| Installation - Steps 1-3 | |
| 1. PLEASE NOTE: In order for video playback to work with this module, it needs to be enabled by factory to work while stopped. If the video playback still does not work with the gear shift in P gear and the parking brake engaged, this overly restrictive setting needs to be removed by a dealer first. Move the seat all the way back first, then firmly grab under the plastic cover with both hands (on the inside) and pull up hard. The cover is held in place by the brackets marked with the red circles. |
| 2. Check the circled spots for T20 torx or philips head screws that hold the side panel in place. If present, remove any screw covers before unscrewing. Take the side panel out by pushing it outward (left) and down. Pay attention to how it interconnects with the other parts, so you can re-install it correctly later. |
| 3. C/E/S Class only: Pull up the carpet all the way along the left side. Beneath it you will find a black wire harness box. Its cover is held in place by plastic tabs. Unclip the tabs and pull the plastic cover up. |
| Installation - Steps 4-6 | |
| 4. S Class: Remove left plastic bracket of driver's seat rail, then lift up the carpet all the way until you see a plastic cover with a black wire clipped into it. This is the part that needs to be lifted up. Underneath is the CAN terminal block. |
| 5. The goal is to locate and work on the CAN BUS terminal block with the brown wires connected to it. It needs to be removed from its bracket. You may need to carefully pry it out with a screwdriver, as shown. Just stick the screwdriver between the bracket and the terminal block while pulling up on the terminal block. |
| 6. On all SUV type cars (ML/GL/R Class) the CAN bus connector is to be found behind the side panel on the driver's side. Lift up the doorsill as mentioned above, then remove the sice panel by just unsnapping it. Locate the CAN terminal block (1) with all the brown and brown/red wires connected to it and remove it from its bracket. |
| Installation - Steps 7-9 | |
| 7. Attaching the wire taps: S Class: RED wire (or RED wire with PURPLE STRIPE, if present) (+12V) and BROWN wire (GROUND). SUVs (ML/GL/R Class): RED wire (+12V) and BROWN wire (GROUND). These taps are removable and only leave minimal traces, which usually stay unnoticed. |
| 8. Attaching the wire taps: C/E Class: RED wire with WHITE STRIPE (+12V) and BROWN wire (GROUND), both going to a black or blue connector. On SLK (R171) use the THIN RED wire. IMPORTANT: The module requires permanent power, so please make sure at the end of the installation that the LED on the module will continue to blink when the ignition is turned off (until the data bus goes into standby). |
| 9. PLEASE NOTE: The plastic bracket must be removed, before any plugs can be pulled out. It is held in place by two tabs on the sides. Push the tabs outward while simultaneously pulling the cover piece upward or stick a screwdriver between the bracket and the terminal block and carefully pry it off. It is a bit tricky to get off, so please be patient and don't use brute force. With the cover gone, the plugs can be removed. The following step explains in detail, how to find the correct plug which needs to be removed and replaced by the one from the module. Connect the brown ground wire and the red +12V wire before proceeding. |
| Installation - Steps 10-12 | |
| 10. Because of the module's universal compatibility and different pin-assignments used by Mercedes Benz, all modules are shipped with just the blank pins on the ends of the wiring harness, along with the needed plastic caps. Insert the pins on the module wire harness into the supplied plastic caps according to your car model. The positions on the plastic caps are clearly marked with "1" and "2". The long thin pins go into the bigger one of the two caps. Top half (C, E, ML, GL, R, SLK, CLK, CLS) RED wires go in position 1, BLACK wires go in position 2. Bottom half (S, SL) BLACK wires go in position 1, RED wires go in position 2. Push the pins into the correct position hole in the cap, making sure it locks into place with an audible "click". After inserting all pins, push the plastic latch on the side of the plastic caps in. It also locks into place with an audible "click". |
| 11. Finding the correct CAN plug - PLEASE WATCH THE VIDEO. Connect the SmartTV module with the module harness (making sure the latch is engaged). Connect the small plug to the CAN bus and tap the unlock button once. Watch the LEDs on the module. Now disconnect the other small plugs one by one (one at a time) until the RED LED on the module stops blinking 3x and instead blinks 1x. The correct plug is now found and can be connected to the matching socket on the module harness. A successful installation is indicated by the GREEN LED blinking. | |
| 12. ALL MODELS: Place the module inside the harness box. Close the lid and make sure all tabs snap back in place. Replace carpet and side panel. Make sure you snap the side panel in place correctly, as there may be tabs that interconnect with other plastic parts of the dash or the hood release lever cover parts. Replace screws and plastic cover. Installation is complete. |
