Dont count on getting much utility (usefullness) from Smelly Bikers maps. Its VERY inaccurate, and you are just as well off with Garmin world map. None of the roads and tracks on Smelly Bikers maps in areas I went thru last year (central Asia, Mongolia and Siberia) were even CLOSE to being accurate, nor were they any more detailed than Garmin World Map that I also had with me. At maximum resolution, the only stuff i could see that was more detailed than Garmins world map, was the rivers. Smelly Bikers had much more watercourse detail, and curiously, identical road details. The additional river detail added nothing to my navigation and was often an annoying distraction dominating my screen.

I have recently discovered the OSM stuff and have contributed a couple of tracks. I think this is much more useful because they are real tracks people have made. The Smelly Biker stuff is just scanned maps from what I can tell. Even the main highway across Siberia is nowhere near accurate and hundreds of people record that track every year. So you would think it should be spot on.

I was quite disillusioned with the maps to be honest. In fact, I would have been disappointed if they were free. I had wrongly assumed they were collated tracks of peoples travels, but they arent. ...and OSM actually is.

I will use OSM in future.
