Am I going to get charged for Sprint Navi?

[Synned]

Hey guys
My family has the Sprint Power Pack Family 3000- $0.0

Plan Features:

• Sprint Power Pack Plan
• Line 1: $149.99 Minimum Monthly Charge
• Line 2: Free
• Lines 3-5: $9.99 Each
• 3000 Included Anytime Minutes
• Unlimited Sprint Mobile to Mobile
• Nationwide Long Distance Included
• Unlimited Night & Weekend Mins. Included
• Nights: M-Th 7PM-7AM Wknd: F 7PM-M 7AM
• Caller ID
• Call Waiting

plan. I know I get unlimited power vision, etc, but I don't see anything about GPS. How could I find out if I am going to get charged for Navigation? I have been using the program for 2+ days and love it, and it says nothing about being a trial version or that I will need to register for it.

Thanks
Joe
