As per title what do people recommend to suit the above. Car is a 03 E46 with the CD head unit and no boot changer. Would like to combine both Bluetooth and aux input within the same unit.

I had the Parrot 9200 which was ok and have the Grom audio setup with the Bluetooth dongle in my 00 E46. The Grom Bluetooth isn't great as the dongle is hidden in the boot but that's my own fault.

So what's the options?
