Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I suspect from the sound of it, that you may not be doing something quite right. Two suggestions:
1. try connecting from the JVC rather than from the Smartphone. Sometimes such connections with automotive devices can only be done from one end.
2. try entering either
which are often the default PIN numbers for such automotive devices.
If the above does not help, then please let me know what model of JVC device is in your car, and I will advise you further as appropriate.
