Can someone please help me?! I have interlock system in my car. I have had this system in my car since October of this year. I have had problems with things going wrong in my car every time I go to my monthly interlock maintenance appointment. The interlock systems are progressively draining my car battery. I just had an appointment yesterday, and I have since lost all my Bluetooth capabilities, my USB charger and media cord no longer work, and my media options no longer work. This is all right after my interlock maintenance appointment. Can someone please lend me advice? Should I choose another interlock company perhaps? Have these issues happened to anyone else? This is a 2014 car, so I have a fairly new vehicle, so these issues should not be happening. Please help!!
