Depends which Garmin. My 1000 has had a couple of 'rain deaths' so I've filled the SD slot with silicone grease and tape it shut. It should be pretty solid now.
After its last rain death, mine has a screen with a slightly yellow tinge and the touchscreen works even less well than normal, which is saying something. It'll be going back for fixing when I find a reason not to just use an Elemnt instead.
