Just got a 2019 Odyssey in October. Recently, the xm radio has been going off and on. Sometimes it will go several days with no signal, other times, just a few minutes, and sometimes it works perfectly fine. It's not a signal obstruction issue. Any idea why the problem is? I need to get in into the dealer for the warranty repair. An xm employee told me I needed a new satellite module. Any idea where this is located?
