OTC has released the Multimedia Interface Tester (MIT) to help diagnose vehicle communication issues on Ford, GM and Hyundai vehicles. The MIT sends a clean signal to a vehicle’s Bluetooth or auxiliary connection to confirm whether or not the vehicle is communicating properly. The device works by connecting via Bluetooth or 3.5mm auxiliary jack and providing an audible confirmation of connection and test. The device is updatable though a USB connection and more OE’s will be added as coverage becomes available. Connection issues include an inability to sync a phone or other electronic device via Bluetooth or an auxiliary jack not accepting audio or video input. Technicians can identify if there is an issue with the vehicle or input device.
