The OTC Multimedia Interface Tester helps diagnose vehicle communication issues, such an inability to sync phones or other electronic devices via Bluetooth or an auxiliary jack not accepting audio or video input, on Ford, GM and Hyundai vehicles. The device sends a clean, reliable signal to the vehicle’s Bluetooth or auxiliary connection to determine if the vehicle is communicating properly. It connects via Bluetooth signal or 3.5mm auxiliary jack and provides an audible confirmation of connection and test. The unit can be updated though a USB connection and more OE’s are expected to be added as coverage becomes available.
