Additional MMS deactivation for Lada Niva
Installing an additional MMS shutdown button and measuring voltage loss in the on-board network BEFORE and AFTER installing the button. The button not only turns off the MMS, but also turns it on. This is the standard control mode. If the radio is turned off via the ACC line (power line), it will also turn on via that line. If the radio is previously turned off using the standard power button, you will have to turn it on using the standard button. Unfortunately, I didn't show the effect of turning on the red button in the video, as I hadn't yet realized it myself.
