oh yes, it cost 9.99 for sprint navigation and if you do not have a data pan you will be charged .03 per Kb which can add up quicklyy butdon'tt worry they are only able to charge 75.00 per billingcycler for data without a data plan..That comes from customers in the past accessing the Internet using 10,000 KB of data usage and receiving a bill for 600.00 so by new sprint regulation if you access the Internet and use more than 2500 KB we canonlyy charge 75.00....which i canguaranteee if you use GPS it will probably happen
