I have a 276C that has the same problem. Garmin has a unit with this problem and is working on a solution. The problem is that the real time clock loses time when the unit is turned off and disconnected from a power source. As a result when you turn on the unit it thinks the satelites are in a different orbit than where they actually are. The unit will continue trying to aquire forever and not find the satelites. You have to select "New Location" from the menu and select "Autolocate" and the unit will start to look for any satelites in view. The unit should get a fix within 15 minutes. This is a very frustrating problem having to reset it every day. There is a new version of firmware (5.3). I don't know if the problem has been fixed with this release.

The Garmin GPS III and III plus use a tabbed lithium coin battery. Its is a Panasonic BR-2032. You can buy these for about $2 from larger electronic suppliers. The problem is that the shipping or minimum order will make that $2 battery cost you about $25. For you cheap guys there is a solution. You buy a CP-2032 and a coin holder. $2-3 for the battery and $1-$2 for the holder. 6 screws to open the case, cut the wires close to the battery as possible. Solder the wires to the coin holder (good idea to heat shrink or cover the solder joints), put in the new battery and you are done the easy bit. You will most likely have to trim away some of the plastic on the holder such as legs or other things sticking out. Unfortunately you can't really do this with out fitting it in the case and you don't want to do that until you have the holder on the wires so it will be in the right place. Once you get that, simply play with it until you can put the screws back in. And tighten gently. Not too much or the gasket will be squeezed too far out. Put tAA'sx AA's back in, take it outside so it has an unobstructed view of the sky, set it down and go for a long coffee or three. It will now download the almanac and any other data which can take 15 minutes or more depending on the satellites. You should see a low battery error and other errors such as saved data lost. Ignore these. You can put it on a external power plug or just leave it off with the AA's and in 5-7 days it will have reset the error as it figures it it now charged. You get the battery error even with a new fresh charged battery. I think there is a Garmin reset code to force this but none of the codes I have tried have worked.

March 2009 I replaced the solder type battery of my GPS III Plus with a battery holder (clip) that a “Basic CR or BR2032 Coin type battery”, without solder connections, that is, they simply clip into place. Replacement batteries can be purchased at less than a $1.00 of E-Bay.
