GPS speedo retrofit to older speedo face?

[samckitt]

Anyone done it? What speedometer did you use to get the parts from?

You can use any aftermarket electric speedo (or just the guts) and then drive it with a GPS unit from Classic Instruments or Autometer.

Why? It's added cost and complexity for zero gain in functionality.

What's wrong with the VSS from your T56?

[samckitt]

Was thinking it might be easier than getting the mechanical speedo to work, & if I change gears/tires then have to recalibrate/reprogram. If its GPS, none of tthat is needed.

VVS, besides GPS doesn't always have a signal.

It's plug and play and calibration is a simple procedure.

VVS? What's that? You mean VSS?

I still have to do something witht he speedometer because now it is mechanically driven. And I don't want to do one of those hokey Abbot boxes, that takes the electronic signal & outputs it as mechanical to drive the speedo. I would rather convert mine to electronic. Need to find an electronic head that is compact that will work.

My gps speedo never loses signal except maybe very briefly under wide overpasses and such. Certainly nothing bothersome.

In Oregon or other mountainous areas it can be. Even my Garmin 276c with remote antenna will occasionally lose reception on the way to the coast or heading up into the Cascades mountains. Also in major metro downtown areas with tall buildings interfere with satellite reception. Really depends on the region you typically drive in.
