开关坏了, might be easier to fix, if I remember correctly, the power button
for a garmin is a square push button switch on upper right corner. If
someone could open it up for you, you will see a small round push button
assembly soldered on the edge of the board. Dirt or carbon deposit could
have gotten in the middle of the 2 contacts, what I used to do is to use a
surgical knife to open up the cover of the push button, and scrape those
contacts clean.

Is there any online tutorial about how to open it? I am afraid to break the
whole GPS.
Thank you very much!

Thanks a lot! Do I have to open the back, as the instruction says? Or just
open the button is OK?
Seems re-soldering needs a soldering tool. Played with that in Middle school
. But I bet it is hard to find one.

You'll have to take out the whole GPS logic board, unplug the LCD flex-cable
, remove that ceramic patch if it is not glued on. leave the RF shield alone
. Examine the push button, look at the back to see if the joints are
fractured in any way or loose. If solder joints look solid, then you'll have
to open up the switch and clean the surface with knife, alcohol etc. If the
joints are loose, then easy fix. By the way, opening up the push button
switch is not easy, it might require some cutting o
