great whether using for mobile conversations, streaming music or retaining XM
(if subscribed), The A2DIY-GM3x works in 2003-12 GM Class-II vehicles equipped
with an XM tuner module (See Fig. 18) regardless of subscription status. If
subscription has expired, an AUX input jack is provided for users to connect and
