of TC's and tunes

[She-Wolf]

hello again folks, can you please clarify;
I need to tweak the TC settings so I can get to my patrol area in something less than a week, and get down the Kiel canal between meals, and several of you have advised me as to what I need to do - but I cannot find any such settings in Options (I am in GWX but do not have any other mods). I also looked in the games files for a certain folder which I understand would allow me to set the TC's manually, but I couldn't find that either. Also, someone mentioned 3D settings - was ist das? Sorry to be so dim, not firing on all cylinders today.

Also, I would like to play three songs from BlackHawk Down on the gramaphone to pass the time ( the crew won't let me in on their card game), can I do that? I see that the gramaphone songs have a different file extension and so suppose I cannot simply add the files to that folder.
