aux in..... hmmmm.... its just a 3.5 jack isn't it? they really suck reminds me of those old cd player jacks for a tape player, the quality of your mp3 player wont matter to much cos you can allways just use the head units equalizer to get best sound quality. Ipods aren't that bad, they acually have a great battery life. and sound isn't too bad if you get a batter set of head phones.
is the high flow the one from GCG sydneykid offering? thats the one i have comming, been waiting 2 weeks now should be here any day.
