Usa Maps Help Please

Hi I Have Just Loaded Maps For Florida Onto My Icn 510 And Used A Brand New Sd Card. When I Check Up For The Information To Make Sure It Is Loaded Ok It Will Not Allow Me To Look Up Addresses, Cities Etc The Options Are Just Greyed Out On The Screen.

It Will Show The Details For Points Of Interest And Let Me Search Them.

The Rest Is Just Greyed Out. Is This Because I Need To Get A Fix In The Usa To Able To Look At The Info And Addresses. I Thought I Would Be Able To Browse Through But It Will Not Let Me.

I Am Off To The States On Saturday And Would Really Like To Know If This Is Normal Or Not Befroe I Go.

I Have Tried Calling Navman And Not Really Had Much Success Other Than Being Asked To Buy A New Card And Load To That Which I Have Done.
