| I have a hm277xl navionics chip that does not show on my lcx-18c lowrance unit. It is an older unit but still works fine. My icons still show on the units global map but the chip map does not show. How can I tell if it's the chip? I don't think they make the chip anymore, how can I get one. Can a place like Cabela's check this out for me? Any information on this would be helpful, thanks | |

Location: Kodiak, AK | You may need to install a more current update. I know my HDS units, even with 2012 chips needed updates to even read them.
