My daughter got a new Chevy that has XM in it. We've both used Sirius for year but always had the portable units, so the look/feel of an indash system appealed to her. When she asked about a lifetime sub for the XM she was told the transfer only applied to portable units--buy a new car in 4 years with XM and you have to get a new full priced subscription. Has anyone else tried this. I don't understand why a Sirius/XM company doesn't operate seamlessly. This is just as weird as Sprint/Nextel merger where they still don't have a seamless operation and it has been a few years. Seems like you should be able to lifetime a system and add units no matter which brand of satellite receiver you have. Makes me think I should sell my SIRI stock except I can't afford to take the loss. Really poor thinking at the marketing level.
