lowrance lcx38c hd card reader

I updated my lcx 38c hd to the newest version 2.5. I purchased the platnium 2010 from navonics and my unit will not read the card. It does however read other cards.
What did I do wrong

You didn’t do anything wrong. There are quite a few issues with Lowrance units particularly some of older ones not reading the Newer chips from Navionics and Lakemaster.

LakeMaster took care of the compatibility issues a few weeks ago.

Not sure about Navionics.

Are you selecting the correct map by using the menu?
If I recall with the X-38’s they didn’t auto read the Nav chip and must be selected from the menu.

Sorry, I don’t have one for Navionics.

I can not even see any maps to select. I go to map data and then to map choices and select navionics. The navionics menu becomes active below but there is no regions to select from the 3d enable becomes active also. I was wondering if the update became corrupted for this portion?

Solved my own problem with a couple of phone calls one to Lowrance and another to Navionics. After the calls it turns out the new 2010 platnium chip is a 4gb and my unit will only support the 2gb chip. I need to return the platnium and get the 2010 premium chip.
As a new user to this site I do appreciate the quick responses and hope to be able to help others in need
Thanks again

Thanks for sharing the fix!
