Reply With QuoteGot enough 5V from your power supply - had similar issues myself, GPS would work and then not, upgraded power supply from M2 to DSATX and it seems to have cleared that up - think I was just a bit low on 5V with all the usb, etc
Hope someone can help. Ok, my car pc has been working excellent the past year. The only problem is I loose the GPS signal when I get the areas of NYC with large buildings i.e. times sqaure, park ave, financial district etc. See it doesnt lose the signal and turn the car cursor from green to red in IG, but it turns yellow or red and jumos me from one road to the other on the screen. It even says im off the rad sometimes. Anyone else have this problem...please tell me you do. Im just about ready to get a new mouse. Just need to know if this problem is common.
This is the one I have:

That's a good receiver (based on the fine SiRFstarIII chip).
What you are observing is very typical behaviour of GPS navigation while driving among tall buildings in large cities. If you do a lot of driving in such areas, pretty much the only thing that you can do to improve the reception of the weak satellite signals, is to place your GPS antenna on the outside of your vehicle - on the roof. If you currently keep your GR-213 inside you car, you will observe substantial improvement when you place it on the roof.
If your GPS location still jumps from one street to the next, then when ever you find yourself in big city downtown, just switch from 3D map view / heading-up to 2D-view / north-up. That way the map will stop rotating senselessly, and you will be able to orient yourself easily, even while your GPS location icon happens to fly across buildings.
Thanks Marvin ill try that.That's a good receiver (based on the fine SiRFstarIII chip).

don't worry too much about it, it happen all the time.
the gps signal bouncing all over the tall building.
I see GPS systems in every other car in NYC. Are you saying theyre having the same problem? Highly doubt it.
unless they have dead reckoning feature on their system, then yes they are having the same problem.
dead reckoning is overriding the gps signal if the signal is not making sense, with the sensor from speed of vehicle, heading (with gyro), etc.
OEM nav units do use speed/direction that help.
But the biggest thing is put the puck on the outside. I had mine in my dash, in my trunk, and now on the top of the trunk. In the dash (up near the plastic facing up) and trunk (magnetic mount stuck to underside of same metal it is on now), reception was horrible. Would take 20 to 40 minutes to lock, and would lose signal in heavy tree areas, and large coverings. No skyscrapers here, maximum city ordered height is 13 stories I believe
As soon as I stuck it outside, instant lock on cold boot, and reception in the garage with the door closed, I never loose signal. 2mm of metal sure does make a difference!

My experience exactly. That's why I'm considering an external antenna. I can't figure out how to stick that GPS mouse (Garmin 18) outside. It is in my dash right now, at the skightest tree/building, I lose signal. Outside the car, perfect, it takes a very narrow street with tall buildings to block it. The roof is the best place by far, period: number of sattelites, speed of locking into them, precision, etc.But the biggest thing is put the puck on the outside.
