Garmin 2820 has bluetooth and is waterproof. $235 on ebay right now with free shipping. It is the same as the one I posted above only with bluetooth. The only bad thing is you have to wire it to the bike, but then again you never have to worry about the battery going dead that way.
Sorry didn't see you said about wanting an audio jack. In that case the one I have is great if you just want to try something out. I got mine for $75. Has the same no battery issue, but is really good. You can get others nearly as cheap, but I wanted to make sure mine was waterproof.
