New hands-free laws are in effect in many states and if your 1st Generation Cadillac CTS or SRX has an XM module; the A2DIY-CTSx Bluetooth kit is for you!

Using a phone in any way while driving can be dangerous, and if your First generation CTS or SRX still runs great but lack support for more attractive modern media formats such as Bluetooth, and if well beyond listening to CD's, Cassettes or same old commercials on the radio; the A2DIY-CTSx is for you! The A2DIY-CTSx kit upgrades Cadillac CTS and SRX vehicles equipped with an XM module (U2K package), to support Bluetooth features only available on newer cars. Hands-free Profile: (HFP) is not only less distracting than trying to juggle a phone while steering but also the only legal way to do it in many states. Music streaming: (A2DP) allows users to wirelessly play internet music, listen to turn-by-turn directions and more. XM radio retention: subscribers retain their subscription, but if XM has expired, an AUX input jack is provided to which uses may connect and play portable audio devices (e.g. MP3 players, Satellite radio kits, iPods etc.). A media remote control is included to change tracks, play/pause, adjust device volume, answer/end calls etc. all while keeping eyes on the road. An optional USB "Smart charging" kit can be added to keep devices charged. After initial pairing, the module (hidden behind the dash) automatically connects/disconnects upon entering/existing vehicle. How can I confirm vehicle has required XM module? Simply press radio's "BAND" button repeatedly until XM is displayed, if only AM/FM is displayed; vehicle does not have required XM module and unfortunately incompatible with this module.
