Um... yeah. I just hooked up a new stereo and two new amps. And I lost FM. And I have I have zero intention of trying to fix it today. (i just spent a few a hours in the sun already) Would love to hear what fixed it for you guys tho. And for the record, I've done this sort of operation on no less than five vehicles in 16 yrs.... This is a completely random experience. I just remembered some guys saying this happened to them, so I'm trying to read up on it before I act.
