Lowrance I Finder H2Oc, I was given the unit and it needs a mapping chip. The unit was purchased in 2009 and is now obsolete. I have searched all over the web, amazon, eBay and all for a SD Card. The max it can be is 1G and really all I fish is Ky and Tn. Lowrance, Navionics and Fishing Hot Spots have been no help. The one I would like to have is Hot Spots Prem, 2009, 1G. Any help is most appreciated
