Helix 7 will not read Lakemaster Plus card

I have a brand new Helix 7 and I have updated to the newest software version. I purchased the new Lakemaster Plus Minnesota card with the Helix. Tonight was the first time out and the Helix will not read the card. Nothing changes with the card in.
Going through the Menu’s I have tried everything. In the charts menu, tabbing down it says “auto” and will not let me change it.
The upper left side of the screen says “NO Card”. The card is in correctly.
The dealer told me to contact Humminbird.
Has anyone else had this happen???

I have a helix 10. Try removing the card and putting it back in. I noticed it was kind of hard to get it pushed in all the way to “lock” in place

David,
They do have kind of a crappy position for the card slot. It is so close to the housing that even getting the card out is nearly impossible.
But to answer your reply, I have removed and re-inserted the card Many times, and it is “clicking” and locking into place.
But thank you for the response.
