I had a few for venezuela, topographically pretty good
reading russian.....sucks...most main roads were there, In venezuela the present dude in charge has'nt built a new road for a decade...so no issues there.
I got mine free from somewhere on the web a long time ago.
There's a free venezuela GPS map available which is really up to date, including Mc D's........they use them as an address system.
two streets south past Mc D take a right oposite the chemists, Maturin venezuela...for example
The link is on my venezuela thread in the latin america section
