Bluetooth module for rns 510

[Jimbobson]

Hi

Would like to install bluetooth in my 58 reg passat cc which has rns 510 stereo system. Would prefer oem or at least an invisible-type installation which can talk properly with the existing stereo unit. Would like it to be compatible with any modern phone including an iphone 5. Not sure if vw have been able to fix the compatability issues of their early bluetooth modules which would only pair properly with Nokia technology from the dark ages yet? Would also like it to be able to stream audio via bluetooth. Does anyone have any suggestions on a sensible unit and where I might be able to pick one up at a reasonably price?

Thanks very much
