I had a previous version of this post and wanted hands-free system and more. First previous 4 years old and I was not laché. The new, with similar operation, brings everything he lacks bluetooth. The telephone conversation is comfortable as an embedded original system. The wireless microphone is long enough, it can be placed anywhere in the cockpit, sun visor (optimum position), or otherwise. Then the Bluetooth system for the music is very convenient, with very good sound quality (it still must that the source does not distort the signal too ...) In short, quality / price top seen the benefit.
