Question about Cobra GPS500 GPS Receiver
The GPS won't acquire a satalite signal with brand new batteries.
I had this problem - couldn't acquire satellites even on mountain top with clear skies. Cobra said unit was defective, so returned for refund. Seems to be a common problem with these units.

of which GPS unit you use, finding sufficient satellites can be
difficult if you are working in an area with trees/mountains/hills or
other obstacles. Here are some suggestions to locking onto satellites:
1.) Mission Planning. If you think you're going to be working in a tricky area, but sure to check mission planning. This software allows you to input a location and obstacles, and gives you the times when satellites will be best.
2.) Wait. It takes the GPS units varying amounts of time to "find" satellites, but if satellites are visible, the unit should lock on within 5 minutes.
3.) Move. If possible, move into an area that has a clearer view of the sky.
4.) Face south. This is especially important if you are using the GeoXT. Turn the GPS antenna so that it is facing the southern sky. The majority of satellites have their orbit so that they appear in our southern sky. There are also satellites in the east and west, and almost no satellites to the north.
5.) Rotate around. If facing south doesn't work, slowly rotate the GPS around 360 degrees.
