Sorry, there was a problem. Please try again later.If your vehicle head unit supports Auxiliary input then all of our SiriusXM dock and play radios and the Roady BT can connect directly to your head unit via Auxiliary input. If your head unit does not have Aux-Input then you can use the optional FM Direct Adapter model FMDA25 to connect any of our Dock and play radios and the Roady BT to your 2005 GMC Sierra. Professional installation is recommended for the FMDA25 as it requires access to the back of your vehicle's head unit.
