- 2005 Buick LaCrosse CXL
Hello there. I have a 2005 Buick LaCrosse CXL with the upscale factory stereo in it. That means that it should have the XM option, but when you touch band, you get AM, FM1, and FM2. The options of XM1 and XM2 are skipped over. Is there something missing from the stereo? If so, what could it possibly be and how do you get access to whatever parts you might need?
