The AVIC-X950BH comes with number of connections, including HDMI, RCA outputs for video and audio, and rear camera input. However, wiring the system could be problematic on late-model trucks when trying to interface with the unit. Cutting into the new truck's factory wiring harness wasn't something we were looking forward to. Connecting the navigation system to the VSS (vehicle speed sensor) helps the accuracy of the mapping, so it needs to be tapped. This made us very nervous. However, VSS signal wire is already in the pigtail wiring plug for the factory radio. This is where Crutchfield and the PAC interface accessory come in.
