Bluetooth FSE Parrot CK in the A8?

Hello, dear Forumians!
Can someone tell me if I can connect a Parrot CK 3000 hands-free system to the Bose system (A8, D2)?

I bought the part at the time and wanted to install it in my S4, but was too expensive because of the two subsequently installed amplifiers.

And before it's just lying around here, I'd like to put it in... If anyone has any experience, please report.
Best regards, Thomas.
