navionics chip

I have a lowrance 332c with a navionics North chip. I was on the upper
St Croix above taylor falls today and the chip was really off. It actually showed me on land when I was in the middle of the river at the lions boat landing on the wisc side of the river. it showed me on land for about 2 miles north until I went around a corner and then it finally showed me in the river, but I know it wasn’t accurate.
I think it was actually dangerous.
I have noticed some of the lakes are off also. How do i correct this? Or can’t I. i have had this chip for a couple of years and have not noticed it was this far off before. What are some suggestions.

Call navionics, they;’ll have you submit a report and then they will check it out. I found some stuff on my ’07 chip and they replaced it with an ’08 when the ’08 just came out.

How was fishing?

fishing was tough. Water ws high and very swift yet. They haven’t moved down from the morthern waters. Water temp was about 58 degrees.
