I had a 2007 map in use until 9/2013. It has tons of GPS tracking shown on it, practically everyplace I have driven since then. The map was outdated as some of the roads were changed, and redone.
Now for the kicker, the 2013 version is not compatible with 2007 maps. So you have to install 2010, import the maps from 2007. Resave them in 2010 format. Then import the 2010 map into 2013 and there you have it.
Locally it appears some roads are still a bit off.
