Question about Garmin GPS Devices
Garmin has a history of internal rechargeable battery problems that go back at least as far as the GPS III Plus. There is a button cell battery in the GPS III that is used to help it "remember" where to search for satellites (according to their tech department). It was supposed to have a 10 year life, but mine failed after 6 and they would not repair the unit. The unit would eventually operate, but as soon as power was turned off, it would lose all routes, waypoints, etc. That is not my idea of a good deal.
The 276C has a similar problem; if you leave it off of the charger for more than a day or so, the MAIN battery is fine, but the unit will not find satellites. There is a software fix for this if you have an older unit but it really doesnt fix it; the fix simply forces the unit into a mode that says "STORED WITHOUT BATTERIES" which is a misnomer; my batteries were in and charged, but I think what they meant is - the internal battery bit it.
If you reset the unit by holding the POWER button and the ZOOM OUT BUTTON at the same time, the entry screen will pop up. Accept the conditions and the unit will attempt to power up. I have had mixed success with this technique. The BEST technique is to LEAVE THE UNIT ON THE CHARGER at all times when it is not in use!!!!
Also go to their site and make sure that you have the latest software 5.4 and save your waypoints, tracks, etc., before you download the new software.

The problem is normally caused by the rechargeable battery.
Open the case, disconnect the battery for 1 minute the put every thing back together. Should work!
