So I bought a used car with an aftermarket stereo an it has Bluetooth on it. Well when I tried to pair it with my phone my phone said please enter the pass key. I have no idea what it is. Is the passkey set on the phone or the stereo. And if it's on the stereo how do I reset it???
Thanks
Well it says dual on it that's the only kind of brand I can find on it but there's a number on it that say XHD7714
