Well i just bought a N3. (FINALLY) and i'm looking at getting xm, a backup camera and a ipod adapter. I was wondering will all these fit to the brain or will i have to get a splitter so to speak.

No it'll all work.

The iPod gets plugged in to the XM and then the XM to the brain (or vice versa) and the rear view camera connects to an RCA at either the brain or the headunit.

ahh ok i see it now so each accessory has a little "piggy back" function and it can just leach onto itself. if i want to get a rear view camera so i can just watch have it on while driving would i just hook it into the rca or is there something special i need to do with it?

There is an RCA input for the camera. It will most likely need a power and ground connection too

ok i guess i just need to get the unit in and play around with it.

Normally, the camera will be displayed when you put the car in reverse, or if you run your navigation display as a split-screen. If you want full screen reverse camera while driving, put a switch to feed +12v to the nav, but diode-isolate the leads so you don't turn on your reverse lights.

Why not just power the camera off a switched line then hook the reverse wire up to the avic. In split screen mode even going forward I can still see behind me with the camera.

If you want the rear camera to display full screen, you need to feed a false trigger to the head unit, so it will display the full size camera image.

Didn't think about a full screen image. Sorry I'm going to go hide in the corner now.

hmmm well like i said i'll wait till i have time to get the unit in.
