How do you want to connect bluetooth to a jack?! You'll have to connect a device with a cable with a 3.5 mm phone jack plug (male)(which fits into the car) to whatever your device needs (maybe a smartphone with a 3.5 mm too). You can use every device with a headphone or line-out connector. Maybe you'll have to use an adapter. When connected you can switch the audio to CD and instead CD the AUX will be recognized.

There's a whole bunch of BT audio receivers you can connect to AUX. I'm using the cheapest one from China, unfortunately it's mono and the sound is contaminated with an unhearable while driving "digital hiss".
I use a cheap bluetooth transmitter I got from amazon. It's made by taotronics. It was only $20 and I can charge my phone while playing music without having a loud hum from the charging interfering with sound quality, like when it was plugged in with the aux cable.
