So I have one question for now and I'm sure more later. This Grid is a friend's and was purchased in 2014 and sat in the box. Do these ever need firmware updates if that is even possible?

Yes.

To update your MSD Grid (PN 7730) firmware, download and install the latest version of the MSD View Software.

Thank you.

Thanks Mark.

I looked at the build date and it's 2019 not 2014.
