Hi All, I have a 2005 RX330 with built-in navigation and the standard audio system. Because the system, unfortunately, has no MP3/IPod connector, I'd like to replace the audio unit with an aftermarket CD player (probably a Pioneer of some sort). I have a couple of questions:
1. Will I have to replace the GPS unit with the audio unit or are the two completely separate?
2. I really like the fact that audio is turned down when a bluetooth call comes in. The audio unit I'm thinking of is Bluetooth ready. Will it retain this functionality? Will it play well with the existing Bluetooth? I
