Don't forget - make sure you get one with a date code (printed on label) of At least (no earlier) than 2008 to be able to receive all Sirius programming available...
For example, units mfg. earlier than 2008 cannot receive 'The Best of XM'
Earlier units will work, but will not receive all channels as the later/updated units will
