You will likely have to install one if it isn't visible on the face of the radio. Sometimes they are in the glove compartment or middle console.
If not, here is an option and here is an option.

I would recommend the second option since you can still use it if you get a different vehicle. Just be sure to double check the compatibility for your specific vehicle.
