Bluetooth retrofit question
So I recently found out I can retrofit Bluetooth into my e90 and it\'s steering wheel (I have the professional sound system). I\'ve read that I will have to use parrot as the retro, my question is where and what do I have to buy? And is there any way I can make it look 100% stock? Because I don\'t like having after market adaptations on my dash. Thanks for the advice ahead of time!
