You are right there isnt Much you can do
But plenty of stuff on the INFO page weather Car parking POIs EMails MMS,
also one feature i like is the WHAT WHERE page you get there by online search
i e POST OFFICE, DONCASTER.
you can also Plan your routes on PC and send them straight to car
They go in the Stored Routes Page i do use that a lot as it gives you uptodate Route Info
Hope that helps
