That
phone uses the Symbian operating system.
Marine applications are far and few between.
A
Google search on "symbian

Fugawi PathAway. Looks like it is about $60.
From the posts I see, people are saying that Symbian is being phased out by Nokia (and everyone else who uses it). So, I would not expect to see any new
software come out for it.
