No contour on mississippi river pool 2

I’m not getting the 1 foot contours on my lakemaster chip in my LowranceHD generation 1. Of course there is no support from lakemaster or Lowrance. It works just fine on nearby lakes. It does show the locations of the wing dams. Is it possible I turned something off? I believe the chip is a 2009

The old chip did not have contour lines.

I am thinking that for the 2009 chip
Pool 2 was not an HD water.
I googled and found some info.
Guess what web site?

As long as your talking chips, If anybody has a chip to sell that will work, I need one foe my my other lowrance HDS (gen 1)…pm me if you have one, thanks

Mine works just fine on P2…I think I have a 2010 or 2011 chip.

So according to the article the 2009 should have detailed contour mapping. Anyone have an idea on how I can get that reloaded?

The 2009 chip did not have contour line for pool 2. Pool 4 and lake pepin had contour lines on that chip.

AND,… Early versions of the 2010 Lakemaster chip missed incorporation of several sections of Pool 2’s 1-foot contours during thier manufacture. They corrected this shortly after being notified.
Unfortunately, mine is one of the early chips that is missing many sections of P2. The first missing link starts right at the 494 bridge in SSP – going south for around 1 mile. As I said, there are several other sections as well.
