  1. Hello Vic. Just saw this post of yours. Curious if you ever found the cause and a solution? I have a similar situation as you (2002 C2 Cab. with the M490 audio package). Curious - is the whine ONLY coming from the rear seat speakers? Mine seems to be. I've been trying for a LONG time to fix this, but haven't sadly figured it out. Not sure what the stock radio/head unit was, but the previous owner pulled it, and put and installed a Blaupunkt Beverly Hills 71 unit. I BELIEVE the stock CDR220 radio chassis is making contact to a metal "tab" on the left side of its dash mounting. directly next to THAT metal tab is the grounding wire of which you speak. SO it is POSSIBLE that your new head unit isn't making contact to that grounding tab. I didn't get a chance to test that yet on my end. In my case the "whine" is constant, unchanging with increase or decrease of radio volume, and has no correlation to engine rev. Matter of fact it exists even if only the ignition key is in the "ON" position.
  2. I know this is an old thread, but wanted to also seek some braintrust input. Seems my 2002 996 started acting up with regard to left front turn signal. Had this same "fast blinking" on the dash and assumed burnt bulb. But it is seeming that is not the case. Changed bulb (autozone's 7507LL orange). The flasher SOMETIMES works blinks as it should, and SOMETIMES doesn't come on at all, and I get the dash "fast blinking". So I'm left thinking there is a ground problem somewhere?? Not sure WHERE to look for that wiring issue. Only the front left signal seems to be erratic, All other's seem fine. So I'm I to look at JUST the driver side FRONT lighting unit and the wires there, or can a "ground" problem be... well... ANYWHERE?? Thanks in advance for the help!
