Regarding the Jeep’s electrical gremlins, a quick google search of the Can-Bus style electrical system on all 2007+ Wranglers should provide you with additional information about issues that have surfaced, and how they affect the accessories you can add to the vehicle. If you would like our take on the issues, stop by the store, as it is too complex to be thorough in an e-mail.
Found a couple threads on other forums. Apparently it's just working around the wires that can cause issues and interference. Brake light signals going off randomly... stuff on dashboard turning on/off. I guess installer error but it's just more complicated.the sound system doesn't hook into the CAN bus. Why would it? it's no different than any other car audio system. Any monkey can connect the wires together.
