Gps Speedo
 

I'm looking to replace my speedo in my H2X. I'm wanting to go to a GPS speedo. I hear they are so much more accurate. I'm looking at a auto meter part number 200845-33
I'm curious to know whats all involved with hooking them up and how do they work? I can't seem to find much info. So i thought someone on here might be able to help me out.

Thanks

If you are lucky the new speedo will fit right into your exisiting speedo hole. Then, you need a signal source. Either an antenna or you can wire it to a GPS. If you have a capable GPS that would be best.

There's lots of info on this site about this topic.

Installation is rather simple. I also think your on the right track with autometer. I had Livorsi in my last boat and I wasn't impressed with the build quality at all. the orange pointers were fading after a year and 2 of the bezels were popping off. I've no experience with Autometer but I can't believe they're worse.

I'm running an autometer marine gps speedo and antenna. It works great and seem to be a high quality gauge. You'll also get a top speed recall function.
