I have just installed the 800/900 but from the following screenshot, you could guess the problem. Two of the instrument panels are corrupted. What could I do to solve the problem. If I have to re-install the 600/700, will i loose the file with the navigation data? I cannot find the problem. The 600/700 version is 1.3, i.e. the latest one. ThanksIvor

I don't see the problem :)This the EFIS-style. In de PMDG menu you can change it (back) to PFD/ND

Ivor,Our best suggestion to you is to consult the PMDG 737-800/900 manual.The first manual is called "Introduction", and as the title suggests, introduces you to the new features of the 737-800/900. It is a wealth of information that we are sure you will find useful.If you turn to page 0-11, you will find specific information about different cockpit display types.Best,Vin ScimonePMDGwww.precisionmanuals.comhttp://www.precisionmanuals.com/images/forum/devteam.jpg
