Today we bought a 2010 Rav4 Sport with the non-JBL, "XM Ready," single disk, factory stereo. When pressing the AM-SAT button the radio changes to SAT 000 or SAT 001 so I know there is an XM receiver present. How do I get the Radio ID number from whatever receiver is installed? Can I get it from the LCD display or do I need to find the actual receiver itself?
