Garmin edge 705.. waterproof to IPx&... what does that really mean?
I know what the standard is... can with stand accidental immersion in 1 meter of water for 30 mins
but how does that relate to cycling in rain
I did a 3.5 hour ride last weekend and decided to pocket my gamin inside of several layers of clothing for safety concerns
would my garmin in theory been fine for a 3.5 hour ride in the wet ?
is there any type of case that is ipx8 that I can still mount on my bike so I could actually see my garmin ?
I've ridden with my 705 in a few downpours without problems, though not any 3+ hour ones, so I can't answer your question directly. I have owned wristwatches in the past where the manufacturer warned against pressing any of the buttons while the watch was wet. Apparently pressing a button breaks the seal in some case designs, but I don't know if this applies to the Garmin Edge (I hope not, that would be lame).
One thing I will say though, is that, IMHO, the memory card cover on the 705 seems like a huge water entry weak spot to me. The latch isn't very secure and I've had mine pop off a couple of times without me realizing it, including one time when I rode with it at least once before noticing the cover was missing (fortunately it wasn't raining, and I was able to find the cover later). It usually comes off when I have the unit in a pocket or bag, and probably accidentally press down on the latch when pulling the Edge out. I now keep some electrical tape over the cover (waterproof tape would be even better).

The 7 rating means you can drop your bike while crossing a river and the GPS will be OK.
The next rating down mean you can ride in torrential downpours.
The unit should be fine in anything.

Water projected in powerful jets against the enclosure from any direction shall have no harmful effects.
