2020 MacBookPro M1 Big Sur - GPS

I am not trying to be a wise guy, I just want to understand:

1) Do you mean a Garmin product that would share its long/lat with the MacbookPro, so I can use the MBP and other software as an additional aid to navigation as I asked? Or

2) are you suggesting I simply purchase a garmin GPS/Chartplotter to use along with or instead of my three other chartplotters at my two helm stations to navigate?

Thanks,

Thanks Bob,

I just bought this boat and the helm in my pilothouse already has two Raymarine e120 12" chartplotters, with radar, autopilot, etc. (the flybridge as a third). While these were state of the art when installed by the prior owner ten years ago, I was hoping to add the more modern navigation of apps such as Navionics and Aquamaps on my mac (if you dont know these apps you should look into them) with a 27" screen at the helm. The navigation apps, cost just a few $$ or so a year and would quickly bring my helm up to date while I figure out if I want to replace the older chartplotters with Furuno, Simrad, B&G, Gramin, Raymarine....make sense? All I need is a GPS my Mac can talk to....and I can't seem to find one, thus the post.

Thanks for your time,

Russ

Thank you,

Is there anyway our macbookpro's can see and use Long/lat?
