Annunciator for GNC-300XL

I have a 300XL which I intend to connect to an HXr that I don't yet have. If I connect both the Arinc429 and serial as per the document in the HX section, will I still need the seperate annunciator panel (MD41-444) or will those functions and annunciations be available within the HXr display? The MD41 has the AUTO/HOLD function and also displays APPROACH ARMED/ACTIVE.

I believe the HX and the HXr use essentially the same electronics and similar software. The HX installation manual has instructions for a 300 install, and says the external annunciator is required. So unless things have changed, I think you need it or something similar.
Edit: These are more than annunciators, they also have a couple of switches.

Thanks Bob
Poking around in the weberator I found a simple diagram, two switches and four led''s, to make your own. Plus the guy I bought the 300XL from is going to look around and send me the real panel if he finds it.
It seems like this is going to be a good combo along with the val remote nav.
