Had problems with my navionics card today while at fork. Only showed lake. No details such as depth and all contours. Anyone know what's up?? Have never had this happen.

Did you pull the card and put it back in? Maybe it would reset things. Also make sure, if is a smaller unit, to change the map area to east texas. I was on tawakoni once and had the same thing happen. Turns out tawakoni is in the north texas region.

What unit are you running as well as what Navionics chart are you using?

Funny you say that, my front HDS10 did the same thing last night in the working man tourney. It will run the insight/Lowrance but not the nav chip. I pulled the chip from my rear HDS thay was pulled up and working fine and installed it on the bow and it didnt work either. I re installed it in the rear and both chips worked on it.

Maybe it was something in the air at fork Cody lol., it's an eagle 642i unit, and yes I tried to pull it out and out back in but still wouldn't work right.. Going back Friday guess I'll try again.
