Garmin Handheld Update
 
Am looking to upgrade the maps on my Garmin GPSmap 76Cx to include good detail in the Adirondacks, primarily for paddling, also some hiking. I guess the US Northeast 24K would be best? If I choose a download installation (over the micro card), will that over ride existing data and maps? Thanks for any info and advice.

I believe so, but you can get a second card.

I have had the 76Cx for over ten years. I looked at the box and it doesn't say what the internal memory capacity is. You need to know the free memory beyond that already being used. The Northeast card is labelled 4 GB (I just bought one and upgraded to a 64ST). I doubt the old 76Cx has enough memory to support the download version.

I suspect you're right. I ordered the card.
