Just having a quick look, seems to be pretty good coverage. Even the roads into Lamanai are more accurate now than any printed maps I've seen.

Nice

Google Maps has added coverage for a whopping 54 new countries. The additions more than double the coverage in Latin America and triple Google Maps' Asian offerings.

Some will no doubt be disappointed to note that much of the additional coverage is limited to highways and major roads, and, worse, some data is outdated and inaccurate, but the Google LatLong Blog promises this “is just the beginning.” The post goes on to say that in the coming months Google plans to add more detail to the existing countries in Google Maps, as well as more new countries.

Here’s the full list of new countries: Afghanistan, Aruba, Bahamas, Bahrain, Bangladesh, Belize, Bermuda, Brunei Darussalam, Bhutan, Bolivia, Cambodia, Chile, Columbia, Costa Rica, Cuba, Ecuador, El Salvador, Fiji, Guatemala, Haiti, Honduras, Indonesia, Iraq, Iran, Jordan, Kazakhstan, Kyrgyzstan, Kuwait, Laos, Lebanon, Mexico, Myanmar (Burma), Mongolia, Nepal, Nicaragua, Oman, Pakistan, Panama, Paraguay, Peru, Philippines, Papua New Guinea, Qatar, Saudi Arabia, Sri Lanka, Syria, Tajikistan, Turkmenistan, Timor-Leste, Uruguay, Uzbekistan, Venezuela, Vietnam and Yemen.
