I already install the gen2 head unit face plate cost me around RM28 at sungai buloh. Gen2 original head unit can support mp3 such as ipod player by using Aux function in ther radio. the Aux cable if you has the bluetoth receiver and bluetooth dongle for the ipod...then the player can play the songs from the ipod. That thing cost expensive also i think. coz when i bought the gen2 is already built in.....but then the sound quality seem disappoint......thats why i change the head unit and the speaker system. Now cannot use the steering button anymore......Front and back speaker housing on gen2 can support 6 1/2 inch speaker.....without potong here potong there....heheheheheh
