So when I set off on a bike ride this afternoon, I tried to make out the strange color along the bottom of my Garmin Etrex Vista's lcd display.
"But, Garmin claims the etrex is rated for 'Immersion for 30 minutes at a depth of 1 meter', and all you've done is ride your bike in the rain."
"Ah, but you see, it's a Garmin... and nothing Garmin says has to be true at all and their products can be entirely defective."
So I don't know what the hell to do about this unit. I can hardly send it back to the USA for yet another rebuild.
I don't know why it leaked. Perhaps because I am using Garmin's own bicycle mount, and it has a poor seal? (Actually... I think that the battery compartment is outside of the immersion-sealing zone. That is, the battery compartment could flood (it could easily with the microscopic rubber seal they provide) but the internal compartment holding the computer stays dry.)
I really wish they'd get themselves in order. Their products are universally crap.
