Unless you had Verizon Navigator and pay monthly premiums, you just cancel that. You can download VZ. Navigator from the APS for free and use it. I am using mine already and I just got my phone on 12/4/11 also. I never had VZ Navigator until now as I didn't want to pay the monthly premium. This is included in your data package.
I hope this helps. You can always go by the store and ask a REp there. Good Luck
