04 toyota matrix xr avic n2

im trying to install a pioneer avic - n2 in to a 04 Toyota Matrix Xr. Everything is stock on the matrix. Stock stereo is a 1 cd/tape/fm/am 2 Din receiver. Can some one do a walk-thru of where i should install the blue hardness wires to? they contain: ill, auto antenna remote control, cellular mute, acc, brake switch.... and lots more... i got it used, so they taped/cut some wires and left me guessing what all those color wires are for. It belonged to an 01 bmw 525i with business cd player or something with business in the stock head unit. they also had a switch to bypass the nav sys so they can use it while driving. If you guys need a pic just ask and i'll get you guys one. installing it with 'Directed audio D2205' amp and a sub box. sorry im really new to installing any nav system thanx alot really appreciate it

Well blue with white stripe will be the amp turn on or remote wire, the solid blue wire will be power antenna not used on that car, Just cap off the ill wire, cap cell mute, red is ignition or switched 12V, yellow is constant 12V, speaker wires are whites,purples,greens,greys, as for the other brake wires and speed sens wires you have to look in the manual because I cannot remember pioneers colors off the top of my head...
