I'm planning on what I am going to need to install a N3 in my wrangler before I actually buy the thing, the install manual is a little vague, If I don't have any add ons (iPod, Sat Radio, Etc) do you still need to hook an IP-Bus cable up between the two units? And if so how long is the one that comes with it? I'm already having to get a extension for the main cable, but I don't know if i'm going to need a longer IP-Bus cable as well.

Thanks!

No the only cable that goes from the brain to the screen is the black data cable. The ip-bus cable only goes from the add-ons to the brain.

Great, thanks!
