The Alpine INE-W940 is an excellent choice for after market auto entertainment. The display format of menu items is superb, the setup functions are a blast, the navigation system gets you where you need to be with voice turn directions, freeway routes and has options to get you to your driving destinations. Music enjoyment is crystal clarity, the separation of music into file and folder formats are astounding. And the Dvd operation is picture perfect. Anyone deciding to implant this Alpine INE-W940 into their stagecoach will not be disappointed.
