Is the speed signal input wire required? Will it function properly without it. I have never understood why this is needed. The thing is GPS! It should know my location, aprox speed without speed signal input.

I have no idea if this the result of no vss hookup..

I have the AVIC-Z2 with Z3 HD from a user here garrettoomey (Thanks again for the great HD and service)

I think without the wire, the accuracy of the navigation is hindered because I have passed a street when the map has me approaching it.

So, I have got the info, where to hook the wire and will see tomorrow

Also slope does not work at all.. So me thinks its an issue.

I do not know if I rehook if I will loose my modded system (hacked) or not.

Maybe someone will post it before I rip the unit out of the car and trace for the connector

look up "dead reckoning"

Hooking up the VSS will not effect your bypass hack in any way.

Thanks for the reply.. it all means I gotta find that connector with the wire.. I did go to Suzuki Pitstop and payed for the online manual for a month.. I now have lots of papers of printed info.

Now to do a VSS search and hookup.

(Have an GMCOL29 but it has no vss whereas the other adapter did..

You may try posting in the "Vehicle Specific Wiring" forum here at Avic411.

I took the plunge and did not hood it up. At times it is inacurate, however it does correct itself quite often. I believe it to be a very minor thing. I would not recommend hooking up the wire if you have to do a lot of digging to get to it, like me.

Thanks to all for your input
