Well so I am looking at using Bluetooth to aux connectors just so that I can cut the cord between my iPhone and the car aux connector. I had rented a Camry on my business trip and it sounded surprisingly great even with its Bluetooth. I thought the Bluetooth might reduce the sound quality but didn't. These are the two that I short listed. 1. Samsung HS3000 2. Griffin technology Bluetrip Aux. Out of these the HS3000 supports ATP-X codec which should provide high quality Bluetooth audio and no loss of quality. I think iPhone 5 also supports ATP-X. Any review comments please. Thanks.
