EDIT: SOLVED! I had to pull the battery cable. No matter how many times I pulled the RCD-510 (like physically disconnected all cables), it didn't help. I was able to put the RNS-510 back in previously and it worked fine, no issues. But the RCD-510 didn't put out any sound until I installed it, then pulled the battery cable for a few minutes. Btw, these cars have an epileptic fit when you reconnect the battery -- got errors for TPMS, steering wheel angle something or other, and other things which wouldn't clear with VCDS. I had to drive around the block to reset everything 
Help! Today I pulled my RNS-510 to have it sent out for a firmware upgrade. I reinstalled my old RCD-510 -- but I'm getting no sound!
The RNS-510 is a version E, and it worked perfectly. I had even rewired the mic to get voice commands to work -- so I don't expect voice control to work with the RCD-510.
But I should have sound, right? What am I doing wrong?
