I just got a AVIC-Z130BT installed in my 03 Maxima. I recently have been doing a lot of driving that requires going in tunnels. Obviously the GPS will not work properly. I realized that the system wasnt hooked up to the speed sensor which according to AVIC411 forum would help resolve this issue. So my question is what wire to I tap into and where is it located?

 

It's coming off the Ecu I'll try to get a diagram soon

 

My God, Pioneer Still needs a speed sense wire ?!?!
