[QUOTE="Saint211, post: 6811317, member: 564903"] Well, tbh with what you just provided it seems narrowed down to either an issue with the FM mod itself or perhaps the power and ground source for the FM mod. So your on/off switch is actually in line with the FM modulators power line? First thing I would try here would make sure there is a direct ground to the chassis or atleast a solid metal support under the dash. Then try different power sources for the FM mod. Lastly I would try running the power line direct without the switch just to be thorough. I would guess its likely that they installed the FM mod and tapped power and ground behind the radio in the radio harness, which isnt a truly direct source. Something to look into. [/QUOTE]
