I've used my car TomTom in a waterproof holder for years. I wasn't going to buy a second device specifically for the bike. It works fine except the display is hard to read in bright sunlight. I've been looking at the Beeline item too as it's compactness is impressive. It also works pretty much how I use the TomTom, ie I'm only interested in the distance to the next junction and what direction I need to go in. Maybe if the TomTom dies I'll invest in one.
