I was trying to install my avn 5500 today,but I found out my stock radio is pioneer and not nakamichi (sp?). So I have to look for a different wiring diagram. My question is, when I install the Nav. sensor that sits on the dash by the windshield, where should I run that wire from? I was thinking about squeezing the sensor through the defrost vent on the dash, but that didn't look possible at all. I seen that a few people here installed their avn on their own, need a little help here. thanks

Also if anyone knows where I can get a copy of the pioneer diagram(or knows what each wire color is for) please let me know, I searched and came up with a couple on here that I couldn't read at all.

(mods if you can please leave this here for a couple hours)

 

you can run the nav wire from behind the radio, towards the glove box, up through the pillar, tuck it between the dash and windshield. Its a long wire.

 

GS300 Radio Wire.
Pioneer
Blue w/ Yellow stripe = Battery +12v
Gray = Acc. or key on +12v
White w/ Black stripe = Ground -12v

 

I did an install 2 weeks ago.
I ran the navi wire behind the glove box, behind the radio.
The speed sensor wire is the top Green one on the 6th pin location. (There are 2 green wires in the same location)

 

What year is your car? I can pull up the wriing diagram for you.
