I have for I week a new A29 Pro dashcam.

The speed inductions comes in the screen after 10 until 20 kilometer
In the beginning with wrong speed. My speed on the video was 83 km/u

Is the a bad gps module ???

If the GPS take a long time to come on, it is often a problem with it.
How about if you have been driving and had GPS okay, if you then take a short stop and then drive on are the GPS then again a long time to turn on ?

 

[pegasusjan]

You are right after a short stop it work immediately
But on the first ride it takes 20 to 25 minutes, sometimes no gps at all after a half hour ride ( this morning to work no GPS after half an hour driving )
I think this is not good

I think you're right, it definitely should not take 25 minutes for GPS to kick in. Mine gets the signal within 1 minute after I leave the garage.
Question is if the GPS module is faulty, or something external has effect on it, maybe some kind of special finish on the windscreen?

I think there is no special coating on my windscreen because my iphone gets gps in the car and even in the garage

not a good way to determine a signal related problem, iPhone uses A-GPS so will supplement with cell tower location data https://en.wikipedia.org/wiki/Assisted_GPS

You right I did now I test with a Garmin Etrex Venture HC see the video. I receive several satellites

still not great signal strength, that's not to say there isn't anything wrong with the GPS but if signal is poor to begin with it can make things worse

I got I new GPS module and now it works find
