think the Google turn by turn on the droid phone is big because it is completely integrated with the phone. You can access a contact with an address...then access your turn by turn to get directions to that contact. Seamlessly. Currently on our TP2...you contact address takes you to that location on the map...but doesn't generate directions (audio) as you drive toward you destination.

Telenav and some others do that...but they require you to pay a fee for monthly service...or they require you to purchase maps for them.

I, too, am partial to telenav. It works well enough for me.
