Getting back into the game, this time with a few questions..

[Woad]

Getting back into the game after a long hiatus, loved the game for it allowed me to say I learned some German from my time on a German u-boat, to which I always get quizzical stares back but I digress.

I'm using GWX 3.0 gold and I was wondering if the mod removes the radio contacts from appearing on the nav screen. I'm in my third patrol and I haven't seen one yet, friendly, neutral, foe, not a one. Is it removed or am I just having some bad luck with that?

The radio messages that indicate some goings on at a particular latitude and longitude, are they happening in the game or are they merely cosmetic? If they are real how do I know where to go since the nav map is sans latitude and longitude lines.

Thanks for your help!
