Weird behavior, please help.

Hi,
First of all i'm new to the world of gps tracking. I'm so new to this world that I don't even know what to search for in this forums to get answers to my question.

The problem I have is with a Teletype Bluetooth receiver. Sometimes the receiver becomes very unstable. It goes in seconds from a fix on 9 satellites to a fix on 2. The next second it has a fix on 5 and the following second it hasn't a fix at all. This behavior can go on for a long time during a trip (say 2 hours). I use TomTom and in the GPS status screen I see many satellites (in gray) and continue moving of red bars (fix) from one satellite to another.

As far as I can remember this behavior started after my experimentation with some GPS software utilities like GPSTweak, Crux view, ceMonitor etc. I don't know for sure. It could be that this behavior existed longer. I started fairly soon with experimenting after I got the receiver Embarassed

What is going on? Is my receiver broken? How can I reset the receiver to factor out that the problem is caused by me? Does a factory reset in ceMonitor totally resets the receiver? If so, than the problem definitely isn't caused by me, cause I did a couple of resets and the problem still exists.

First test for me would be to stay still and see if the signal fluctuates in-car. If it does, take the GPS outside of the car and check again. It may be that you have a UV coated windscreen which dampens radio and GPS signals.

Secondly, playing with the GPS is a dangerous thing. However you wouldn't be able to really do anything that would make the GPS fluctuate this much, the worst you could do is enable XTrac if it had XTrac which I doubt it. You may have enabled WAAS/SBAS if it supports it, and this will reduce the overall sats to 10 instead of 12
