Bonjour,
Désolé de remonter ce sujet, mais j'ai exactement le même souci sur le même appareil.
Après avoir supprimer les deux slashes, la commande shift+7 fait bien apparaître une fenêtre.
Mais celle-ci est minuscule et noire et reste noire même après l'avoir agrandie.

J'ai bien la jauge indiquée dans le dossier "gauges" de FSX, qui n'est autre que la traditionnelle fs9gps.cab.
Mes recherches web n'ont pas donné de résultat.
Auriez-vous une idée lumineuse ?

Voici le panel.cfg de l'appareil :
