Next year I'm planing a bicycle tour through Asia,
Thailand, Cambodia, Vietnam and probable China then South Korea

I have looked at the maps that Garmin offer, they cost a lot 99.99pounds and don't cover all the areas i want, so i have to purchase others

I'm wanting also Myanmar, Laos, and the above (Thailand, cambodia Vietnam China and south Korea)

What options do i have for free maps? Open street maps, MALSINGMAPS.COM and Birdseye view, Free subscription for 12 months

are they any good for what i want, touring about in the above countries and the option to do hiking in the bush.

any recommendations would be handy

thanks in advance
