GPS Digital Speed Meter with MPH ，Car Head Up Display for All Cars, USB Cable Plug & Play

It works wonderfully and actually is very accurate. Love this item for my 1994 truck ,until I cal replace the speedometer cable.

This devise is NOT ACCURATE and displays speeds about 5% faster than actual travel. Also, it is difficult to read it on a dash in sunlight.

Wasn't sure if it would connect to the satellite easy, because of some review. Take 1-2 minutes and bam, it was connected. Shows clearly what speed you’re doing. Great product for the price. Very accurate.

It works as advertised. Its mounting could be better but works well.

Works perfectly. Very impressed.
