If i buy a kaico now will it come with gcvideo 3.0d?

Hello, No at the moment they are on 2.4D however our new stock which should be with us this month has been upgraded to 3.0d

It’s been a couple months since the last update, is 3.0 shipping yet?

Hello, Yes the latest batch which is available now is on 3.0D Hope this helps

Does it have the option to switch from 4:3 to 16:9?

Yes, it does have this option. It reduces the quality of the picture by a little though.
