I"ll be driving cross-country in August (bucket list item every year - new route), knowing the OnStar and sat. radio will expire around the 20th. Timing should be perfect!

I let both OnStar and XM expire on my C6 after the free period, although I did renew XM for six months ($25) once when I was taking a trip, but paid with a paper bill. Even then you must call to cancel or have them renew you automatically at the top-gouge price. It became too much of a hassle so I just didn't renew again, and probably won't with the C7.

With OnStar I understand you still have the emergency service and the cell phone app works for five years whether you're paying them or not. That's all I'm interested in anyway.

XM will turn you on periodically, usually coinciding with a holiday, with limited functionality at no cost.
