Some questions on the Garmin Quest for motorcycle & car use, and the occasional use sailing & hillwalking. 1) If you get the version preloaded with Europe maps what is the detail level like? Are all the smallest roads/tracks included? 2) Can it give OS grid refs? 3) Can it give Lat/Long? 4) Can you load nautical charts? Which ones? Cost? 5) On the bike I'll want to connect it straight to the 12v battery terminals. I asssume some kind of adaptor exists? 6) Will it come with a clamp to fix it to bike handlebars? 7) Are additional/replacment memory/batteries available and easy to install? 8) Without access to a PC is it easy to set a route with multiple waypoints to ensure you take in specific roads/sights on a trip? 9) Is most functionality available without access to a PC? 10) Does it give distance to next turning? (ie Prepare to turn left in 10kms?) 11) Can you change or update the pre-loaded maps? 12) Is there a cheaper equivalent? 13) Can you load OS map data to it?
