I've been reading about these on www.mexicomike.com
(fun place to read some Mexico ideas) where he has a time limited deal to get them for $75 rather than the regular ~ $99 & they come directly from Bicimapas . He says they are much better than the Garmin version. I wasn't real impressed with the Garmin Mexico version when riding with Muleboy that had it on his Zumo in 2009 . I have 550 Zumo to which I would have to load it from my PC after buying the program. I currently use the Guia Rojo atlas to plan & solve route issues & a Rough Guide fold map in my tank bag for on the road use.
Comments, experience with the GPS version from Bicimapas?
