You may already have that, if at least one of your MFDs has a built-in GPS and if everything is already networked together.

We foound an external GPS to be noticeably more accurate that an internal GPS in a shaded MFD, though.

Ours happens to be the external mushroom GPS that came with our AIS but probably everybody makes one.

You have to enter the menu/setup system on each dependent unit to select whatever GPS source you want from among those on your network.
