Hello everyone I have a countrman cooperd with Boost CD radio with aux.
I would like to mount the USB and bluetooth, what solutions are there to do a retrofit parts oem?

 

This worked great for me

 

hello I have also the same model, in fact I have the BT-455.
I wanted to mount the original system of the car with the possibility of using the steering wheel controls and all of the functionality of the system.

thank you
