Enjoy commercial-free music, exclusive concerts, the most sports coverage and the biggest names in news and entertainment. XM brings "Radio to the power of X" to your car and home. The XMR400 (four receiver) and XMR800 (eight receiver) radios provide the ability to satisfy everyone on-board.  Managed with a single XMC100, or integrated with your preferred cabin management system.  Provide you and your passengers their own private XM radio for their listening pleasure - or - provide a ‘pre-selected’ number of channels to all passengers, similar to many commercial aircraft implementations.  Either way – everyone enjoys a wide variety of audio programming.
