I recently bought a bike that came with a Garmin Quest sat nav. I know that they are pretty ancient now, but it seems useful enough, and I have Navfree on my phone as a backup. I've seen many people complain that the Quest doesn't have enough memory for them up upload routes etc.. I'm confused. The device already has European / American, etc.. (delete as appropriate) maps on it. Why do you need to upload further maps with your route?
