I'm not so lucky like u guys using head unit with built-in AUX output.

What i did is install a pre-amp (use this to switch/select audio source between CD/radio player and my iPod) and connect it to my amp. Pre-amp with wiring only costs me about RM150. Connection from pre-amp to iPod = RCA/stereo link cable.

Of course, if you want true line out, get an apple dock or PocketDock (by Sendstation). This will give u better sound quality. Still waiting for someone to organize a PocketDock bulk.
