Question about Garmin GPS 48 GPS Receiver
If you know your coordinates, enter them on the position screen.
Use the track pad to highlight the coordinates on the position screen. Press "enter". Use the track pad to change the digits to match your current position. Place the GPS where it has a clear view of the sky and wait. If you have a power cord, plug it in as it may take as much as half an hour. Do not move the GPS while it is trying to acquire. The antenna should be vertical.
If the GPS still doesn't acquire, it may have lost the satellite almanac data, which has changed since that unit was manufactured. I could not find a software update on Garmin's website for that model, however, it is possible to transfer the almanac data from another garmin. Post a follow up message here and I can give you more instructions if needed.

There's a function in the menus somewhere that you have to check, that does something that must be necessary when changing location in the order of 100's of kilometres since it was last turned off. The default algorithm must assume you are not far from where you last turned it off. You have to prompt it to 're-set' itself. Look for the keywords in the menus "NEW LOCATION". Set it and you'll get a position.
