Aquiring Map

I have a LMS250C, that I bought a couple of years ago. I've installed the update! My problem is, I turn it on and it shows downtown Tulsa OK. That is where it is made or was! I live in Coweta, OK. Outside of Tulsa. I can not get it to show my location. I just tried it for the first time yesterday. I reset it soft and hard. Same thing! I can move the cross hairs to were I live. I doesn't say acquiring or anything. I found the area it said satellites, it didn't show anything? So what might or is going on??? I want to go out Sunday and use map to run in a new area of lake I've never fished before.( boat and I have been down for a couple of years, Sick)
Sonar looks okay! Wired like book showed ! Have the card hot spots for this area. Help?
