M-NAV Display (Small) Available- Fits L-NAV as Well?

I have an uninstalled and near new 2.25" (small) M-NAV vario display
available to trade for a large one (3.125"). The small version is
usually the sought after one. When you fly old or weird gliders like I
do, there's often an abundance of panel space so I can use the bigger
one.

I believe that the M-NAV and L-NAV units are interchangeable, but
someone might know better.

Let me know if this would work for you.
