Yes I know this isn't the GPS section but it tends to be very quiet there. Hema have introduced a GPS the Navigator (link here) which combines a full turn by turn street navigation street GPS with support for all Hema topo maps (pre loaded) and OziExplorer created maps and routes. From a functionality point of view it looks like it may be almost perfect with one big but. Unfortunately it's designed for in car use so it would need some sort of weatherproofing to be viable on a bike. Lets hope a weatherproof version is in the wind. BTW the RRP is $999 the same as a Garmin Zumo.
