Installations could be as simple as plug-and-play (OBD II devices) - just a device insertion in the OBD port, or advanced - requiring certain wiring. When accessories or special wiring are needed (starter disable, driver FOB, SOS button, sensors, etc.), proper evaluation is required - therefore implying a customer-specific cost. A monthly subscription plan is needed for every device, function of cellular data upload frequency to our Web server. The overall cost is mainly a combination of: device cost (one time fee), device installation cost (one time fee) and monthly subscription plan (recurring) - all including access to our Web application and technical support.
