I have the Garmin GNS 530W installed but can't seem to be able to turn it on.
Any thoughts?
Think I had this after the first update - have you set COMM/NAV1 on in the default avionics first? (Turn all the standard fit stuff on, then select the GNS option from the ALT menu options). Similar to the lack of ident sound in A2A GA's with RXP/F1 avionics selected...
Hope that helps.
Nick
