Bluetooth adaptor

Lots of choices on Amazon. You can get one that plugs in to an aux jack or one that transmits on FM.

if you mean for input to the Jensen ? YES

if you mean for output from the jensen to something else, ? maybe not

the USB port on almost all vehicle audio is configure for input only
it reads files or reads the signal coming in from adapter. usb stick, etc..

it may not, send audio out on the usb for blue tooth head phones or speakers

I use a Belkin on my Jensen.

Beat me by milliseconds!

I got this for my dad to use in his 2010 Vette. He's a smart guy, but not totally literate with the Bluetooth-type things. He loves it. And I didn't have to help install it. Totally plug and play. Goes in the Aux port on your Jensen.
