I'll second that Oyster. The deal is they are using data from INEGI, the Mexican version of the USGS. I have been told that a lot of the GPS data is also from INEGI and has many of the same errors. I have checked Google maps against the GR and it is correct where the 2011 edition of the book is wrong in a few spots.
But I have to say that my Gui Roji has never locked up on me and it has never lost power or needed a re-boot. I have never had to charge it or change a battery. It doesn't work that well when wet, the pages stick together but its is still usable. Another plus is that you can swat flies with it, something you should not do with your GPS
