The New Maps are not very good, you cannot see an aerial view and the quality is poor.
There is a solution, which has already been muted somewhere on this page but if it didnt work for you try this for an idea.
install firefox as a browser
install greasemonkey as a plugin (look under addons in firefox)
open up the addons, and opne up greasemonkey user scripts
do a search on the user scripts page for "Geocaching.com extra map layers" omit the quotes !
or simply keep searchin down the pages, at the moment is appears either at the bottom of the first lot or on the second page.
install it.
Bobs your uncle ! the old maps are back
