Topic: Additional maps for a 365i

[daver6322]

I need a map for a specific lake in Ontario.  Can I download one, put it on an SD card, and load it into my unit?

No, you can't download one...

Short of buying a Navionics card, you can at least have the lake contour in your unit.

Just use google earth to click the contour of your water body and import it inside your 365i using Humminbird PC
