I had a similar problem with my Lowrance 334 c igps unit.  It ended up being a problem with the SD card drive.

Can your unit read other SD cards?

Seeing as how that is an older unit (discontinued) my guess is that you will have to go under settings and choose map. The default is to the Lowrance map. You want to switch that to Navionics (not navtronics). The unit should then read the card.

Again, you have to go to menu, settings, select map. The default in the old units is to the Lowrance mapping !!
