Car Radio BT 5.0 AUX-IN Adapter KCA-121B Auxiliary Aux Audio Wiring Ai-net Replacement for Alpine

DOESN'T WORK THEREFOR IT'S USELESS! Item arrived at the end of the given delivery window. The device on itself does not function. The design is flawed. The Alpine car radio will not detect any auxiliary device, because this device only delivers the analog audio signal and does not power the pin that informs the stereo of an auxiliary device. Without modification of this adapter, the car radio, or both, this device doesn't work. The modifications require experience in the repair field and some advanced electrical engineering knowledge. The fix is only theoretical and I have not tested it, so it is possible that it might not function at all and that this device might never work and be completely unusable.
