Re: new to me Garmin 182C
Likewise, I wasn't sure of the question. I have a GPSMAP180, with a discontinued G-Chart cartridge for Lake Champlain.
From the Garmin website FAQ,
"Where can I purchase a G-Chart or Micro G-Chart pre-programmed card?
Older Garmin marine chartplotters used a mapping card called G-Charts and Micro G-Charts. Both G-Charts Micro G-Charts mapping were discontinued in November of 2004. Garmin no longer produces these cards, so they cannot be ordered.The only way to purchase a Micro G-Chart card is to search the internet for other individuals who are selling their old cards. The mapping on any Micro G-Chart card purchased will have 2004 or earlier mapping.
G-Chart cartridges cannot be reprogrammed. If your cartridge happens to be for Montreal / St-Laurence Seaway / Thousand Islands or similar and you'd like to trade for my Lake Champlain (with a bit of Montreal, IIRC), that would be great. Otherwise we're both stuck (not that I'm using my 180 any longer, current boat is Ray E-series).
