GPS and the speeedometer

t(rex) · 02-11-2006, 11:23 AM

I just put a GPS in my 2004 gto. when I connected the wire to the VSS the speedometer stopped working. Any ideas? Is there anoter place to catch the speed pulse besides right after the ECM?

My Garmin GPS only requires a 12 volt connection and does not require a speedo connection, what brand GPS do you have?

What on earth are you screwing with the VSS signal for?!

I have a Blaupunkt travel pilot Dx-v
it has a gyro and a speed sensor in case you loose satalite. Bad thing is it won't work without the VSS. Problem is I think it is sucking too much power out of the wire so the speedometer isn't getting the signal.

Check out this forum, they have a section dedicated to the VSS connection on nav systems,
