From the How To section, thought it might have a better shot here...
I emailed Pioneer, on this... below is what they said. Did anyone find if there was a closer place to grab the signal from other than where frack showed us? IE in the radio harness?
ME: I have a 2004 Mazda 3. The VSS data comes over a CanBUS wire which is serial (digital). Will this work with my unit?
PIONEER: The VSS connection on all Pioneer, in-car navigation is compatible with digital or analog speed pulse signals.

The short version is that our car do not have a VSS wire at all becuase they use the newer CAN bus system. I've heard that you can use the ourput shaft speed sensor found in a two pin plug on top of the transmission (accessable from the hood). I have never tried it myself but it seems like it would work. There are several threads on this subject with pictures of the plug. Another option is to buy a CAn interface for a car from a company like DEI, PAC, or Soundgate.

I am installing AVIC N3 and I am having trouble with connecting the speed signal, I tried connecting onto the engine harness but I guess that is a digital signal.
Where is this signal located that can be used by the N3, or do I have to buy a speed sensor by Pioneer?
Also has anyone attempted to keep the Display, I connected it but it only shows the ambient temperature.
