maybe not so fast..... if its a "stock radio" then your problem maybe be elsewhere. As mentioned, other modules can cause a problem with the data system. One of the "known problems" is when the LGM modules starts "babbling" because of wiring issues.... the "babbling" results in the radio being "waken up" because it is responsible for providing "audible notifications" for things like "open port / door" ( you know those anoying dings)... which things like the LGM might be continuously reporting.... so you do need to check at least that module out... disconnect it and see if you notice a "long term change" in draw.
