i want to put in a pioneer avic n1 into my z. i already have a mounting bracket, and 2 plug setup, but when i pull the stock head unit, the stock head unit has a 3 plug set up. i have the the bose system. can some one help me out on what to do? im just not trying to spend a lot of money having to rewire the system for a head unit.

 

the 3rd plug is for a the cd changer..for the bose system.you will have to either replace all your speakers evenutally.since the stock bose system has a x ternal amp you will need to locate and remove as well..you can run your new deck to the stock bose speakers..but you wont be happy with the sound..hope this helps
