I've seen devices in cars on windshields that measure speed, what are they called and where can I buy one?

I know it's probably common knowledge, but I couldn't find any info with the search function.

Thanks in advance.

Radar detectors can display your speed.

 

It's an amber colored display device that you see in drag/street races. I'm assuming it's a GPS device that tracks speed and distance.

 

this is the most common.
its called a "vbox". there are 2 popular versions. this one (windshield mounted). then theres a "video vbox" which allows you to record what youre doing, shows a digital speedometer, g-force meter etc).



is this what youre talking about ?

 

Yes that's it! Thank you!

It's been driving me nuts trying to find it.

 

Look for the new VBox Sport. Has integration with your iPhone/Smartphone and has an easy to use display. about $425

 

The best $20 app I spent on the iPhone... Harry's Laptimer.
