AMHVMU G4s GPS Smart Speedometer, speedometer car,Speeding Reminder and Fatigue Driving Reminder,USB plug and play,suitable for all car

I was sceptical about this product as there was only a few reviews but credit where it’s due, for £15 this product is fantastic

This is quite a neat little unit and works well, although it requires a 5v (not 12v!) power feed, best supplied from an ignition switched circuit in the fusebox. A suitable dashcam power lead will do the trick - check that the usb connector is the correct shape.Having installed the device and enjoyed the fun of getting it working I have to report that it works very well, although in the cold light of day I have concluded that much of the readout is of no great use to me. My vehicle has a clear, easily viewed speedo and I have no use for the other facilities.So in conclusion it is a super little device if you find its features attractive and useful.

It illuminates but that's about it. Followed the instructions, drove for miles, parked stationary in an unobstructed location but it will not connect to the GPS signal. I'll be returning for a refund.

I was excited to get this device. The numbers are large enough for me to see and I hope it's correct. My Speedo has a mind of its own Sonics been using my phone. GreatPros:The size of the numeralsEase of fitting to the windscreenCons;I had trouble deciphering the instructions for setting up as the translation isn't spectacularThe device only works whilst attached to the lead so that's a nuisanceAll in all the device will be used but I'm not as excited as I was at the idea of it.

Brauch nur manchmal etwas in Gebieten mit wenig Satelliten.

L'afficheur de vitesse fonctionne bien, le calcul de la vitesse est juste. Il remplace mon compteur de vitesse défaillant sur ma 206. L'écran est bien lisible. L'appareil en lui même est bien. Ce qui n'est pas bien c'est le support ventouse qui ne tient absolument pas. Il faut que je trouve une solution pour le fixer autrement car la qualité de la ventouse est très mauvaise. Cette ventouse est inutilisable mais je pense pouvoir adapter la fixation sur un autre support. Ce qui fait chuter ma note à 3 étoiles.
