This is a 2 part question:

1) I’ve got a Lowrance HDS 10 Gen 2 Insight USA graph. Bought in 2011-2012. Hasn’t been used in 8 years. Apparently the Navionics card I used to use ain’t in it…so I have no mapping other than the Lowrance mapping that comes on it (which isn’t much). Can I buy a new Navionics card and just put it in the graph or am I going to have to update my graph before a new Navionics card would work in it?


2) Lowrance HDS 5 Lake Insight model. This graph was bought in 2009-2010. Same question as above for this graph


Any help appreciated
