BTI-ISO
This is the CRUX BTI-ISO Universal Bluetooth Hands-free with A2DP Music Streaming Kit . Yes it is universal and can be used on any vehicle, including those without a radio! This kit is connected via a 4 speaker lines (front left & right, rear left & right) and has a built in amplifier, so it can be used even if your vehicle does not have a radio.
The way it functions is to go in-line between the audio source (radio) and the speakers, so when a call comes through or when you wish to stream music, the BTI-ISO automatically interrupts the radio audio output, and outputs the phone call audio or music audio directly.
NOTE: Not recommended for vehicles with factory/OEM amplifiers. Specialty interface harnesses may be required for these applications.
