Thank you for the reply it's the deafult 737-800 panel (no stack showing in the 747-400 and 777-200) I have tried the above with no sucess. The stack in 2D is just a black box.
Today I have been on my PD3v4 to do a flight using the B737-800 with the default panel but for some reason the radio stck is blenk in the 2D and 3D panels I have searched everywher but cant find a fix, any help would be apprciated. Thanks
