I believe Google Maps has a limit of 1,000 individual points. And quite possibly Google Navigation too.

Also, you might look at:
The free [Only registered and activated users can see links. ] or the $0.99USD [Only registered and activated users can see links. ]. Not too sure of their applicability to what you're looking to accomplish .......... Just a thought.

And if you don't have that many points you can simply locate in Google Maps online and send directly to your phone.
