QUICK "How to do Garmin GPSMAP update from SD card" 

Great video, I just bought a Garmin GPSMAP 743xsv. I am going to have it professionally flush mounted. I noticed that there is an SD card in one of the 2 slots which is in the rear of the unit. I am not sure what's on the card. Should I leave it in or take it out. I did install a blank card into the second slot, what should I do?

I ask for your help, sir, give us clear knowledge on how to update Bluechart on Garmin 923xsv and Garmin 65cv, because we, as Garmin users, have a lot of trouble with this, thank you.

I have a 742xs. How do I get the card from you ? How often does Garmin update software

I bought the Bluechart G3 Vision version 2021 but haven't used it yet, is there an update when it's activated,

Hey there. I just got another 1243xsv to pair with a 943. Is it possible to share custom combo views or do you have to make custom views for each unit?

If you put the microSD card in and it doesn't give you the menu automatically, is there a way to get to the menu through settings? Same unit you are updating in this video. Garmin 1243xsv.

How do I buy the card?
