Connecting SiriusXM to a Garmin RV-BBT601
The RV-BBT601 is SiriusXM compatible but requires an SXV300V1 Connect Vehicle Tuner from SiriusXM. The diagram depicts the back of the RV-BBT601 dock and the circled area by 14 is the plug-in for the tuner.
After the tuner is connected to the dock, the Radio ID on the tuner should be recorded and then a subscription can be purchased from siriusxm.com
