Just fitted a Bluetooth receiver onto my existing older (early 2000's??) Pioneer headunit in the mini. It offered BT as an extra optional accessory, but the device, if it can still be found, was well over $200. I found a generic type made for Pioneer headunits connecting via the IPS bus connector (typically used for CD changers). Only cost $20 on Amazon. This plugged straight in to the HU and after tapping in to switched power & ground lines (not one of the USB powered type BT devices), seems to work well, streaming from my phone.
No more swapping out CD's frequently for me.....LUXURY!
