    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 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.

    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!

    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.
    Installation - Steps 1-3
    1. Turn the ignition off and pull the key before installing! Move both seats and back rests all the way up.
    2. Remove both carpeted covers behind the seats. Grab in the slot below and pull forward firmly.
    3. Visible in this picture are the four rubber grommets (1) and the two snap locks (2) that hold the cover in place.
    Installation - Steps 4-6
    4. Remove the cover plate in the middle by pulling it off. It too is held in place by snap locks.
    5. Remove the four torx screws.
    6. Open the upper storage compartment and remove the one torx screw on the inside.
    Installation - Steps 7-9
    7. Remove the console piece. In order to get enough wiggle room, the upper cover needs to be pulled up hard while gently pulling the console piece out.
    8. Disconnect the plug for the storage compartment light. Then remove all torx screws around the silver aluminum back plate. Take the back plate out.
    9. Behind the plate is the top control box. It has a yellow, a red and a black plug going to it.
    Installation - Steps 10-12
    10. Disconnect the yellow (1) and black (2) plugs by pushing down hard on the locking levers while pulling them out straight.
    11. Connect the yellow plug from the module harness to the top controller and the original yellow plug to the matching socket on the harness. Do the same with the black plug. Make sure all connectors latch securely in place.
    12. Stow all connectors away in the hollow space in front of the top control box.
    Installation - Steps 13-15
    13. Connect the SmartTOP module to the 16-way plug on the other end of the harness. Tap the unlock button on the remote once briefly to wake up the system and check the green LED on the module. It should blink slowly. Remember to configure the module settings according to our Operation and Programming Manual. Use the supplied velcro sticker to attach the module in any open space on the shown aluminum "shelves".
    14. Optional but recommended: Install the supplied USB cable with the module in the car. The small round opening for the emergency top mechanism is located perfectly for this. Remove the small round cap.
    15. Run the USB cable through the opening and connect it to the module. This way it will be accessible for later firmware updates or module configuration via laptop. Put everything back together and configure the module according to our Operation and Programming manual.
