Navionics Chip Not Showing Lake Detaiils ... HELP!

[NCLaker]

Need some help asap. I'm not seeing any lake detail using my Navionics Premium North 2008 chip for the first time in my Lowrance Expedition C (similar to an H2OC). This is the first time using this chip. I assumed all you did was pop it in and it just works, that is all I did with my lakemaster chip.

Can anyone help me understand what I am doing wrong?? Need to resolve asap, cause I plan to using it starting Thursday 9/3.

Also, is it safe to assume all the waypoint I saved using my Lakemaster chip will not be lost once I start using my Navionics chip?

Thanks!

You will have to go into setup and choose that chip. A problem that I have with my H2O is that it will barely make contact so I have to put a folded up piece of paper on top of it before I put in my batteries.

Jim nailed it on the head...If memory serves me, you have to go under the "Map Data" option and change the chip and choose the area of Minnesota you are fishing in.

Thanks for the quick help guys ... I think I kinda got it figured out. Boy is that a pain in the keyster having to explicitly select the area of each state you want to look at - don't understand why you would design it to do that. On top of that, after initially looking at a lake detail, it seems to be noticably slower at refreshing as you zoom in compared to my Lakemaster chip.

I'll continue to play with it. Thanks again!
