We just got In a 2003 Navigatior loaded with evreything. The only problem Is the Navigation Is set to the previous owners address how can that be reset??

It depends on the month/year of manufacture. There's two Nav systems used in 2003; One prior to Feb.2003 and another After Feb.2003

Unfortunately, their completely different systems, different looking, different operating manuals.

I have a zip.file with both systems I can send you via email.. Your profile here doesn't allow emails.
