歷經3周，花了10多張的小朋友換了車上的音響主機。首先，為了要保留車上撥桿及顯示幕功能，特地遠從英國訂購了轉接器，接著開始找尋可支援之SONY MP3主機，且要有Aux-in的功能，終於換上這台完全符合我的需求，其實這中間幾經波折，包括跟店家講解我的想法，他們不能理解為何aux對我來說如此重要？在他們的認定上覺的你的CD可以撥放MP3為何要外接MP3 Player？那是因為我常在車上聽mp3廣播節目，為了可得到更好的撥放音質無需再透過轉換(如FM介面)，所以這些節目若燒成光碟實在是太浪費，也因此我終於可以避開爛爛的FM傳送品質了！

Recentely I start to study how to make my car's sound system to add-in mp3 protable player. Before to study I had use FM transmitter but the sound quality is too bad.

Then I find my car headunit spec. Here have something usefaul to reference. When see this document I think it need to re-design my sound wire. I give up this idea. There have another way. Then Connect2 is solution. If got this product I can change sony headunit including aux-in function. Although they are not available in Taiwan, they accept fax order. I just orderd yesterday and they will send to me. When I recevied it I will survey which sony headunit is better for my car.
