I just installed my GPS speedo, and now I am pissed I don't get to try it out until spring
There are some really neat things about this...the face is customizable (though when viewed at 6" you can see some pixilation), it displays max speed, and the digital readout keeps going after you pegged the needle. Does 0 to 60 times and some other cool stuff. Also has a hot start feature that acquires the satellite really quickly. Price was good too. The only downside is they are really thin and use a spin ring rather than the standard long studs...soo...if you want to use a trim ring, you have to drill and tap that, and mount the gauge to the ring and the ring to the dash.
