I keep reading that people are using the AUX input for mp3 players but I don't see any AUX input on my N2 brain??? I'm trying to connect my creative mp3 player. I would think the N2 has an AUX since even the stock stereo from my bro's Civic has one.

Its RCA inputs that are marked A/V input

the aux cable does not fit into the RCA inputs. It seems the RCA inputs are too small. Which RCA input are you supposed to feed it into anyways? It seems there's a R, L, and video.

What aux cable are you trying to use? Just go to radio shack and buy a headphone->RCA cable. Plug in the red and white RCA cable into the red and white on the deck. Run the cable to wherever you want to keep the mp3 player, and plug the headphone end into the headphone jack on the mp3 player. Make sure you turn on the input in the initial menu too

Is it better to do it this way or with an ipod kit, if I am using an iphone?

With an n2 it's better to do what whtcrxghst said. The ipod interface is crap on the n2.

Well I just bought an RCA to Headphone cable today and will try it out tomorrow. Thanks
