\r You can use Sirius XM with our radios, but you can't connect and control Sirius/XM on the radio itself. You will need a stand-alone, separate tuner or you can connect via the Sirius/XM app on your phone and play Sirius/XM via Bluetooth. Our radios cannot be used with the SXV-300 direct SIRIUS/XM Tuner. And adding the hideaway Sirius/XM is not always easy to install in classic Corvettes, Mustangs, T-Birds, or any car with limited space behind the dash. However, two options exist.\r\rConsider purchasing a radio with Bluetooth and add the Sirius XM app subscription for your phone. The advantage is that you now have access via your phone, anywhere. The additional cost to add the app subscription is usually much lower than adding an additional radio to your subscription.\rThe Sirius/XM DOCK AND PLAY units (Onyx EZ, Onyx Plus, Stratus 7, etc.) can be added by playing them through the RCA Aux input. Advantage: using a Dock & Play unit allows the user to have only one account for multiple vehicles by using additional car docks.\r\r
