I started experiencing weird audio issues, like the volume goes up and down, crackles, and, if I'm using radio, sometimes it will seek next radio station on its own. CD sometimes does work and the sound is perfect.
Here's a sample video of how it sounds on radio (and aux):
Lexus priced me at 2k for replacing the whole unit, and ebay has lots of second hand ones for ~10% of the cost, but they all look slightly different to what I have.
I could either fix the whole thing but this can prove to be difficult. Is it possible that the amp is responsible for the volume/crackling, in which case I can just replace that for now? Anyone had similar issues?
