Yes, it is.

Dear James R. Brigham,
Thanks for your inquiry. You need to manually turn it on when you get into the car everytime and then the receiver could automatically connect with your phone device(If you phone device had connected with this receiver before). Please feel free to contact us if you have any problem. We will try our best to help.
Thank you.

Yes it has a female 3.5 on the device but comes with a double male adapter.
