Question [Q] rSAP Bluetooth Protocol

Hello guys...
I have one question. My 2010 Passat CC has a bluetooth carkit incorporated. But unfortunately it uses the rSAP bluetooth connection. So...for this phone, is there a custom ROM that supports this type of connection? Stock .681 for sure doesn`t support because i`ve tested today. I don`t want to change my phone so I`m looking for a custom rom that has support for rSAP.
Thank you!
