It works!

March 31, 2014
Installed less than 30 min. Interfaced with my 5" autometer speedo, and that was it. Did the calibration advised by AM gauges, and it flawless. My garmin and iPhone apps match the speed. Very easy to wire. I don't know why it took me so long to install this, but wish I did over a year ago when purchased! Like everything I bought from speedway, I'm pleased as always. Thank you speedway.
Pros:
  • Very easy to use
Yes, I recommend this product.

This GPS Speedometer Sending Unit will work with any speedometer that uses an 8 or 16 pulse signal. You will need to check with the manufacturer of your speedometer to be sure it will be compatible. To wire this item you connect 4 wires (two of which go to your speedometer) and you are done.

This GPS speedometer sender works just like any other GPS unit does. I have been running this for a little time now and haven’t had any problems. First I had this mounted under the cowl and it worked but not as good as I would have liked, so I mounted it on the back side of my seat in a 51 Ford pickup. Now with having the GPS in the open it can receive the signal through the glass in the vehicle and has nothing to interfere the signal. I can not see how this would have any problems around corners or up and down hills. I can’t say about the rain but I have tried this at slower speeds and up to the speed limit, ok maybe a little over, and it has always worked well.

Just installed one with my AutoMeter electric speedo. Simple install and works great. Reads from about 2-3 mph, matched the side of road speed sign. Didn't see any drop-outs driving around through wooded neighborhood. Mine is installed under the dash about in the middle of the windshield, but my Corvette has a fiberglass dash. On a car with a metal dash you probably will need to mount it on top of the dash.

The GPS sender will work with 8 or 16 pulse speedometer but unfortunately I have not found your VDO gauge on the list of applicable speedos. You will need to check with VDO direct for pulse rating requirement

I'm sorry to say that we are not familiar with Mercedes speedometer sending units either. I would not advise you to buy this until you could determine what pulse rate the sender operates at.
