2015 Chevy Equinox

Mine was accurate for the first 6 months since buying it used. Coincidentally or not, it started someone after I ignored the 4th request from Syrus xm to subscribe to their service. I was not a customer, but apparently my vehicle was by the previous owner. Once the sale was entered into the system by the dealer, Syrus got my info and started mailing me offers. I think they disconnected something so that the clock doesn't get updates from their service. But, even with manual time set, it still enda up incorrect within a day. I'll let you know what the dealer says when I bring it in for service

Every time I turn my car off when parked my radio volume always goes down it never stays at my listening level
