Product Details

Universal BT45 Series Bluetooth Music & Phone Interface by USA Spec®. This product seamlessly integrates your vehicle's OEM sound system with Bluetooth™ enabled devices so you can make hands-free phone calls and wirelessly stream audio media. This model is designed for universal application. It will work with any vehicle with a factory AUX port or with any USA SPEC PA series product. If you have an older vehicle that is not equipped with a factory AUX port, but is compatible with one of our PA11 or PA12 series interface, you can connect the BT45-AUX through the PA series RCA port. Can be added to vehicles with existing factory Bluetooth™ systems that have unsatisfactory sound quality or are defective. Connect and use two devices simultaneously: one device for phone calls and the second device for music streaming.
