navionics in lowrance

 One of my mates put a navionics card that works OK in his older lowrance GPS in a Lowrance 5500c and when you look at map data it show about 6 files that are a combination of letters and numbers where it should say thevenard to perth,bunbury to broome and so on.

Any ideas ?

 Maybe give the card connections a clean, maybe dirty or have some corrosion?  Mine did cause wasn't shown map data, so gave it a good clean and seems to work fine now.
