Question about Garmin GPS 48 GPS Receiver
The GPS unit i have turns its self off after 5-10 mins and will not pick up any satellites.what would cause this?
It is probably one of the following:
In 1999 the GPS satellites were reset and the new almanac data had to be loaded into the GPS 45 for it to continue to work. It was not uncommon for that model to quicly kill a set of batteries when it is having difficulty acquiring, which would cause it to shut down in order to save the batteries for its internal memory.
I just did a quick search of the Garmin website and it appears they no longer support that model. If you go to their support page and send a request for a software update they can probably e mail it to you. The update is free but to down load it, you need a PC interface cable (RS232 serial port connector) Part Number: 010-10141-00 Suggested Retail Price: $ 38.09.
To rule this one out, borrow an antenna from another Garmin 45 or Garmin 48, or plug the unit into an external antenna and see if the unit still shuts down. The drawback to this method is that you can buy a new GPS that is superior to the one you have for about the same price as an external antenna.
If your batteries are low, the unit will automatically shut off to protect its internal memory. I tried a lot of different batteries in my 45 and I found that Eveready alkaline batteries worked best. Rechargeable nicad batteries don't work very well because they fool the battery meter. Newer models have a setting to specify that you are using rechargeable batteries.
Ultimately the best advice I can give you is buy a new GPS. For less than $150 you can buy a new model that is more accurate, more reliable, stores more waypoints, has a better display, is easier to use, and gives you more valuable information.
