I just bought this h/u and was curious on where the speed detection circuit lead is....according to the pioneer instructions you must connect the headunit to this lead so it knows how far the vehicle travels.....i have searched but have not beeen able to find where this is located....if someone could help me out i would really appreciate it....thanks

 

Im pretty sure its under the glovebox. PM me with what your year make and model is and I can find the wire and where for ya

 

The wire your looking for is right there in the factory stero wires, tap into the purple with white stripe this is four your VSS speed sensing, when you set your Factory radio to use the auto sound feature, when the car goes faster the volum will increase, when the car slows down the volume decreases.

This is also the same wire used for the cruise control if you have it.

 

yeah I sent him the wire. I didnt know it was there on the Scions. Most Pioneers use the voltage input and "sense" how much "noise" the alt is making. Thats cool that they are doing that. Fords been doing it also

 

forklift,

I just went thru this mess with my XB, but it is well worth the trouble the Avic D3 is Bad ___!!

 

I know, I just put it in my Silverado yesterday morning. Im loving the iPod video part of it through the high speed connector

 

Hey everyone i just wanted to say thank you so much for the information it def helped me out alot!

 

TC86,

Did you get it all wired up yet.

 

i have everything wired up except that vss wire im gonna do that this weekend...my dilema with this head unit is it doesnt fit right i mean i cant put the trim ring in because the h/u doesnt sit at enough of an angle....im using the stock brackets for it....did u or neone have the same problem....how did u fix it? thanks

 

fixed it by using the correct kit to bracket it in there

 

TC86,

I had the same problem, if yo goto crutchfields web site they sell the Metra install brackets that screw on the side of the stock brackets and fill the sides real nice
