I had some issues with my lexus after mixed the battery poles, had to get ECU reset and change a lot of fuses. Everything seems to be working but the volume/power know on the OEM radio (not ML). Radio seems to be working, cd plays, but the volume know doesn't work (along with the sound. No sound at all from the speakers).
If I try to adjust the bass/fidelity to test if the know works - same thing. Can't adjust by turning it. Only power the radio on by pushing the ****. Any suggestions? two weeks with no music now ;(

Anyone? Could it be that my amp is dead?

Have you tried replacing the radio receiver itself to see if it'll work with another one?

not yet. Trying to understand what my options are before I invest money into repair (and realize it doesn't fix the issue)

Sounds like an amp issue. When my ML amp was grounding out after light rains I had a similar issue. It turns out the amp was tripping and going into protect mode. You may have fused a few wires together with that battery mix up if you got the money try to find another one on eBay.
