Directions And Compasses ?

Hello,

Am not a pilot, but was wondering about this.

In commercial aviation, and I guess for private flying also, when
directions are given, are they assumed to be True or Magnetic ?

What do pilots use these days for direction ?
I assume a gyro compass of some sort but am not sure. Is this correct ?
If so, is this Magnetic or True ?

I can't believe they spend the effort converting from one to another.
Do they ?

Are chart roses they use shown as True or Mag. ?

What's in the cockpit ?
Do they still have a Mag. compass there ?

Any thoughts would be most appreciated.

Thanks,
Bob
