Today the radio volume control on my 11 Terrain has quit working. I now can only control the volume using the control on the steering wheel. I was just wondering if anyone else has had this issue and if so does the whole radio have to be replaced or just the volume control. I am not too concerned about this as the vehicle is under warranty and the dealer will look after it. This happened on my last day of my xm trial period and I was going to sign up. It will cost me the same if I would of signed up now or wait till the radio is replaced. XM would charge me $35 to either transfer to a new radio or to reconnect so I guess I will wait till it is fixed.
