That's what I say. He has XM satellite in the plane and a car stereo with CD as well. My dad has his ADF sitting on a shelf with a few other instruments that were removed to make room for newer devices or obsolete. The written test has 5 questions on GPS and 18 on ADF. I know it's still used in Mexico and Canada/Alaska. Places I'll probably never fly to.
