umm didn't your avic come with the installation manual? it shows you exactly how to install the deck.
if you don't have the manual a quick search online will help you...
ever tried the pioneer site?
here ya go... Pioneer USA - In-Dash Navigation
if you're not sure how to install the deck i suggest you take it to someone who knows how, thou installing a deck isn't that hard. speaker wires, remote if you're using an outboard amp along with the RCA wires, parking wire, illumination wire, usually a mute for bluetooth, and of course the ground, battery and ignition (in that order). as well as anything else required by the pioneer decks.
and obviously disconnect the negative terminal on your battery. done.
i had the sxact same thought last night about midnight..... so i went to pioneer and downloaded it and printed it out
now i have to figure out a box setup for my 2 10's
thank you for mentioning that
i feel like a fool for not thinking of that sooner
