^^ You need AUX in dude... The best audio you can get. I'd recommend the
Belkin Tunebase. It has a flexible goose neck that stems from the cigarette adapter. You dock your iphone/ipod on it, and it charges it (1st and 2nd gen). It has 2 user set presets and a line out too. The FM scanner uses 'clearscan' tech that searches for 'empty' stations. It worked just fine for me.
I'll stop here, I didn't intend on hijacking the thread.
@OP: That is really cheap (price wise). I wouldn't mind just trying it out lol. For $11, you can't go wrong...
