Starting to read throught FMS section of the JS-41 tutorial and the following question comes to mind.If we already have the latest Navigraph procedures (0909) for the rest of the PMDG aircraft, do the terminal procedures that come with the JS41 overwrite any of these with older versions? Should we re-install the Navigraph PMDG 0909 procedures after the JS41 install?

Use the custom install settings, and uncheck the navdata to prevent it from installing over the files you have. There are only two options in the custom install: the airplane and the navdata.

Ah, now that's thinking ahead on the part of the gent who developed the installer. Good thinking... Thanks for the info Dan!

I am assuming that for those that "forget" to uncheck that option in the installer(they had this on the MD-11 and 747 installers as well), you can simply re-run your navdata updates correct?

Scott, I would assume so. I certainly don't know anything that would stop you from doing that.

Scott,Once the FMS was at a point where we could begin testing it, I'd routinely rerun my Navigraph installer for the PMDG data with each new beta release. Which data was being used in the JS4100 installer was never discussed with us testers as far as I know, but the "reinstall" of Navigraph data worked just fine.

Just delete the contents of your navdata and sidstars folders and then rerun the Navigraph 0909 installer and it'll put all the latest stuff back in.We made repeated requests to navigraph about including the latest navdata with the J41 and we never got a response from them... old version in there for now at least.

Gents-If the installer detects that newer versions of the many navigraph files are present, it will NOT overwrite them. You will see it sort through them in the installer window- but it will only overwrite the existing file if it is an older version.That being said- if you have a navigraph subscription (And we think all of you should!) you can always delete the entire navigraph contents and reinstall them after installing any PMDG product to ensure you have the latest and greatest!
