	Improved compass operation. Fixed occasional map zooming issue. For units used in France: Suppression de la fréquence 155.125MHz. Dans le cadre de la mise aux normes franÇaises des appareils de chasse, la mise à jour - 4.40 - des Astro 320 doit être obligatoirement effectuée par les utilisateurs. Cette mise à jour supprimera la fréquence 155.125 MHz, jusqu'à maintenant intégrée pour des raisons techniques et de distribution au niveau Européen. Seule la fréquence haute 155.600 MHz est utilisable légalement en France et ce dans le cadre d'une souscription à l'association ACUFA. L'ACUFA et la société GARMIN travaillent en étroite collaboration avec les différents organismes d'Etat concernés, pour permettre aux utilisateurs, des appareils Garmin de chasse, de bénéficier de nouvelles fréquences. Cette mise à jour est obligatoire. GARMIN décline toutes responsabilités en cas de sanctions pénales, due à l'utilisation d'appareils qui ne seraient pas aux normes.
