I'm thinking about getting one. I currently have a KDCX998 and LOVE it, but it's not marine grade, and I'm thinking it got a little too wet last summer. I have a biketronics cover I use, but I got caught in some major downpours. The display sometimes either locks up or goes blank. So, I'm gonna see if I can get it covered under warranty. Not holding my breath, but I won't let them know it was on a bike. Anyway, the one I asked about is marine grade and has plenty of options. The main thing will be peace of mind when I get dumped on with rain again next summer.
