I ended up with the non SXM compatible entertainment system on my used, recently purchased 2016 CX-5. We are planning some long distance trips and would really like to have satellite radio. Has anyone purchased this SXM tuner module from Vais Technology? They have a couple of dealers / installers near me. $270 after rebate. They claim their device will not void Mazda warranty and seamlessly integrates into the existing system. Thoughts?
