I own a 2004 G35 Sedan and was considering installing an aftermarket head unit. If I currently have a Sirius tuner and subscription, do I need to notify Sirius that a different head unit was installed to continue service? Or, does the subscription only involve the tuner?

Thank you very much

 

if you have the factory sirus you need to call em and tell em you have a new tuner

 

You will need the S/N of the new unit.
