FAQs
1. What do I do if my new radio won’t turn on?
If your new radio won’t turn on, it’s possible that the wiring connections weren’t made properly. Double-check that each wire is connected according to the wiring diagram and that each connection is properly insulated with electrical tape. If the connections are correct, there may be an issue with the radio itself or with the electrical system in your Jeep. Consult a professional if needed.
2. Why is my radio display dim or not visible?
If your radio display is dim or not visible, it may be due to a wiring issue or a problem with the illumination wire (orange). Double-check that the orange wire is connected properly and that the radio’s dimmer function is turned on. If the issue persists, there may be an issue with the radio itself.
3. How do I troubleshoot a speaker that isn’t working?
If one of your speakers isn’t working, it’s possible that there’s a problem with the wiring or the speaker itself. First, check that the wiring connections are correct and properly insulated. Then, test the speaker by connecting it to a different audio source or by using a multimeter to test for continuity. If the speaker is still not working, it may need to be replaced.
