GPS Speedometers

Has anyone tried a new GPS Speedometer? Not requiring a mechanical hook up it would be great for custom rides.

I've bought one from Speedhut, but it's not yet in use, as the car isn't quite finished.

There is a free app for I-phones called speedometer,its a gps speedometer. Just lay it in the seat it does the rest.

 

I use the one on my DROID all the time.

 

Beat me to it. I use it whenever I'm in the Lincoln as the damn cruise control unit is broken and that means speedo no worky.

Just need to find a speedo drive gear for a '60 Lincoln cruise control unit, oughta be easy to find, no?

 

I have a Garmin ... GPS and I used it in my 32 3W until I could get the speedometer calibrabed and reading correctly.

Modern technology is GOOD at times.

 

A GPS is all I use !

 

I've been looking at one from them. How about your thoughts after you get it.

 

mine is form cl***ic instruments works perfect

 

i use a speedhut type on my dac lambretta, and im very impressed

Do they get "dead spots" around trees, tall buildings , hills etc?

 

only if your driving thru a tunnel ,we have some overhere but signal is restored after a few seconds

 

It's all well and fun until the satellite dies! HAHA!

Me, I'll stick with direct-read speedometers.
