GPS speedometer replacement (update)

After a lot of crawling around and investigation I have had it with trying to get my VDO speedometer working right. I am going to go to a Speedhut Legacy 0-100 mph gps speedometer. A simple install and a good looking speedometer that fits in the existing hole.
The only drawback that I struggled with is that it relies on satellite to get the speed information. I started thinking about the number of times that I had lost sat signal using the GPS and it is very very rare.
maybe in a tunnel or very tree covered roadway but I can't remember any time other than the Eisenhower tunnel. I can manage that OK. I keep to the main roads that accommodate my MH.
Please tell me I am not crazy.

I have installed the GPS Speedometer and all is working very well. It came with a hotwire feature that when connecting to an always hot wire you get an instantaneous sat acquire. It is right on the money with my other gps and is very fast to respond. For me this was a great fix.

  • I use mine as the accurate one anyway. Never lost signal for long and you may have a reset button on it if you do. It will reset in about 30 seconds.

    We have a speedometer on our standalone GPS (Garmin). It follows us nicely, but always registers about 2 mph slower than what we are really going. There is a slight delay as it communicates back and forth with the satellites.


    There shouldn't be any delay since the GPS device only receives information from the GPS satellites and it does so at the speed of light!

  • I many times only look at my GPS display while driving. It gives me a map of the area, current speed, and what the GPS "Thinks" is the speed limit on that particular road. It can be off on the speed limit signs posted along that route, or might not give any speed on the smaller roads.

    So try a dash mounted GPS, it should work fine. At $100, they are a great price too.
