That depends on the production date of your car.
Maybe, your bluetooth is installed under the carpet of the boot. Check if you have a module there, near the backrest of the right seat.

If you don't have it, your head unit is bluetooth and usb capable.
If you have the module you have to see if it is a MULF or a ULF. In the first case, usb retrofit is possible with a few pieces, but if you have an ULF, you have to upgrade to MULF which is more expensive.

Why don't do it by your self?
Retrofitting is always possible!
