I have had multiple Nissan cars. When I ordered my 2011 Nissan 370Z the dealer told me it comes with a BOSE sound system that included Sirius/XM. I have a Sirius account with multiple radios and planned to transfer my former Z account to the new 370 when the free trial period was over. That day came and when I called Sirius/XM they told me that when it comes to billing they are separate and I couldn't use my Sirius account to activate the XM radio Nissan installed in my Z. They say I have to create a second Master account at 2 times the price of my Sirius Master account to be able to listen to Sirius/xm. It sounds like a PROFIT maker. They want to be 1 company until it comes to billing. I have called them many times, spoke to several people and they sent me an e mail saying we have no plans to change that policy in the future. Sounds like Nissan needs to push Sirius to make one radio and stop this foolishness with 2 types of radios. Nissan doesn't have a way to call and voice my opinion but I called the dealer and vented all over him, next time leave out the sound system I put a better system in the car. Thanks for reading my post
