    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.
    Detailed function description (* = Factory setting)
    Function 1 - Main Switch - Workshop and Diagnostics ( 0=OFF / *1=ON )
    The module can quickly and easily be enabled and disabled using this function. It acts like a master switch. When disabled, the module becomes completely inactive and behaves as if it was not installed.
    Setting 0 disables the entire module while keeping all other function settings intact. This allows turning the module off and back on without the need to reconfigure all of the other user configurable settings.

    IMPORTANT: In order to avoid problems with diagnostic tools and to avoid confusion or injury by unexpected top movement, we urge you to ALWAYS DISABLE the module before taking the car to a shop or lending it to a third person! If problems with the top arise while the module is installed, ALWAYS contact Mods4Cars first at www.mods4cars.com. NEVER take the car to a dealer without getting support first!

    Function 2 - One-Touch for the soft-top switch ( 0=OFF / *1=ON / 2=AUTO ) - Setting 2 requires Firmware v1.10+
    When enabled, the center console switch operation is enhanced as follows:
    Holding down the switch in either direction will operate the top as long as the switch is held.
    Tap "OPEN" to open the top.
    Tap "CLOSE" to close the top.
    Tap either direction at any time for emergency stop.

    Setting 2 (Auto) opens the top automatically when the mechanical latch is disengaged. USE WITH EXTRA CAUTION!
    Auto open can be canceled by immediately tapping one of the top buttons after unlatching.

    Function 3 - Maximum allowed speed for top operation ( *0=0kmh / 1=10kmh / 2=20kmh / 3=30kmh / 4=40kmh / 5=50kmh / 6=60kmh )
    Setting the max allowed speed for top operation in steps of 10km/h (~7mph). Setting 0 only allows roof operation while halted.
    WARNING: Once the top is started within the programmed speed limit, it will continue running, even if the speed later exceeds the limit during the top operation!

    Function 4 - Warning Beeps ( 0=OFF / *1=ON ) - Firmware v1.20+
    If the mechanical latch is not engaged within ~5 sec. after closing the top, the module will produce warning beeps via the cluster beeper.

    This module is equipped with our interactive setup feature to allow easy setting of the desired options.
    All programming is done by using the center console roof buttons (1) and (2) and the cluster buzzer. Functions and their settings are indicated by beeping patterns of the buzzer. Navigation is done by tapping "CLOSE" (1) for next function or "OPEN" (2) for next setting. After selecting the last function or function setting, the setup automatically jumps back to the first function / lowest setting. Each time either a new function is selected or a function's setting is changed, the buzzer will indicate the new status by first beeping the function number, followed by a short pause and then the setting number.
    To enter programming mode, first make sure the ignition is fully on. Hold down both buttons (1) and (2) simultaneously for about 3-4 sec. (or until you hear a long beep) then let go. The buzzer will now indicate function 1 and its setting. Either 1-1 for ON or 1-0 for OFF. From this point on you can navigate through the functions by tapping "CLOSE" and once the buzzer finished the beeping pattern for function and setting, change the setting by tapping "OPEN". The new settings are active immediately.

    To end programming mode, either wait for 30 sec. or tap both buttons simultaneously. End of programming mode is indicated by a long beep.
