I do have 2008.1 for the last 3 weeks now. But unfortunately I mostly drive in the city and have not had a chance to go on the toll roads.

I do notice some changes from 2005.2 (which is what I was using before I upgraded to 2008.1). There are a few newer developments that did not use to show up in 2005.2 although they were in existence then that are now in 2008.1.

Sorry, I cannot be of more help.
