Where Do I Find A Gps Navigator Software That Doesn’t Need To Be Connected To The Internet While Navigated?

I have a Nokia N78 hp that has an internal GPS. I really need a gps software (symbian or jar) without the need to connect to the internet while navigating. Downloading maps with internet is acceptable but not while navigating cause it make a large hole on my budget while using google map navigator as an example. A surprised gift for anybody who could help me with this.
