In search of the discontinued G chart for Lake Michigan, at least the southern half. Anybody?

What is a "G Chart?"

My apologies for not being clear. A G Chart is from Garmin and is a navigational chart to be inserted into one of their GPS's. They are discontinued and have been for many years. I have the choice of going back to my old Garmin GPSMAP 215 that uses G Charts. They, I believe were replaced with BLUECHARTS in later models. The built in world chart will suffice for what I need but not nearly with the detail as with a chart card. I have a northern Lake Huron I would be able to exchange for the Lake Michigan chart or I will just pay someone for it.

Thank you, I hope I cleared that up

I'm sure you are watching eBay, something will probably pop up eventually with enough time. On a side note, do you have an alternate plotting system for navigation? I have an old Garmin running the Bluechart chip (bought used chip off eBay) but I would not rely on 20 year old charts as my primary source for navigation. Channels shift, buoys are moved, new hazards may now be present.

I use Navionics as my primary nav software. For a $15/yr subscription I can run this on multiple devices, including a Samsung Galaxy tablet that I bought for $50 and my phone as a secondary device. Granted I'm not doing longterm cruising so the need for a full chart plotter is not there. Sounds like you may be in the same boat smile

Thanks Ajax

You're right I'm not planning on long term cruising with this boat. Have dug out the GPSMAP 215, 3 shades of grey color and am installing it on my "day sailer". i will be sailing it from Chicago to NW Lower Michigan and wanted a detailed chart installed in it.

thanks again, still looking
