Question about Garmin GPS
This problem can occur when the map file is corrupted or can't be read. Try putting your sd card in a reader and deleting the GMAPSUPP file (in the GARMIN folder) and fitting it back in your device. Then reload the map from Mapsource onto your handheld.

Try re-setting your gps by simultaneously pressing the Enter and Page buttons while turning it on if that doesn't work check your firmware i found the latest one v 3.90 would shut off my gps when recalculating v 3.70 is stable Garmin know that the new firmware can cause problems

I had the same problem. Reluctantly, I removed the batteries and the 8 phillips screws from the the case back perimeter. Be careful on opening. The unit is designed to open from the top and hinge at he bottom to keep the ribbon cables from being stressed. The unit should open nicely and lie flat on the table with the two bottom halves butted against each other. Get a magnifier and ensure the printed circuit board attached to the bottom half has all 3 screws. (I found one missing that has 2 functions - securing the board and delivering battery power. Mine had wedged against a piece of clear plastic...it was hard to find!!!) I carefully removed the wedged screw and returned to the circuit board left most attach point. Close up the unit and we were back in GPS heaven. Battery power restored!!!! and my $250.00 still in my pocket. Yipppeee.

when the unit is on try to press and hold the reset button for 10 seconds and then release if this will not work charge the unit for 3 to 4 hours using a wall adapter and if still not work try to check if there is a latest firmware update for the gps then download it.

SOURCE: I tried turning on my
These units seem to be suffering from a bad connection on the inside of the unit. My wife's did the same thing. There was a connection inside that wasn't making contact. First try cleaning the 4 brass connection tabs on the watch and check your charger to make sure the tabs are raised and not squished. Second try to reset the unit. Hit mode reset and power buttons all at the same time. Hold these for 3 seconds and then release. If these do not work here is what I did. There are no screws holding the unit together. I used a exacto blade to very carefully pry the unit apart along the side seam. It's not easy to do. Be very cautious and gentle. Work the thickness of the blade into the joint to gently wedge apart. You are not trying to remove material! Once apart you will see some fingers that make a connection between the upper and lower part of the unit. This is where the problem was with my wife's 305. I gently raised these tabs to make a better connection, It's been working ever since. I didn't try it before but try pressing very hard on the unit where it says Forerunner 305. The case is very hard so it might not work. But if it powers up when pushing you found your problem. Hope this helps. Here is a link I found on opening a 205 (Same process) http://ctorunner.googlepages.com/dismantleforerunner205 To put the unit back together use Automotive silicon/gasket maker. Use a tooth pick to put a VERY small amount of silicon around the entire seam. Put the two half's together and wrap tightly with electrical tape. Test the unit immediately to see if it powers on and off. If it does not open it back up and raise the small prongs that make the connection from the bottom half to the top half. If any silicon squishes out the sides wipe with water and a rag. Let the unit sit over night. In the morning remove the tape.
Let me kinow if this helps.
