Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

I have installed a PCM unit, thanks to the detailed instructions found here on this great forum, and it doesn't work as it supposed to. When I push the power button everything turns on and I get a message: no navigation, no phone and no amp. I understand that I don't have nav and phone right now but what about the amplifier? I think this is why I get no sound through the speakers. Help somebody... PS: I don't have Bose.

POST 2Original post

Odd but it sounds like your car is programmed to think it has those items (including Bose) and thus reports them missing and sends no sound. A trip to the dealer to put the car on a PIWIS machine is likely in order.

POST 3Original post

The system has to be entered into the MOST system and CAN to be operational. This is done with a PIWIS tester. Best , Scott

POST 4Original post

I thought that this is the problem, I will go to the dealer and keep you posted. Thanks

POST 5Original post

If its used, then it is programmed for those items, and now they dont exist. Dealer will fix it.

POST 6Original post

I have the same problem with my PCM and the dealer couldn't fix it. They said that the PCM was for a bose system, and since my car didn't have the bose system, they couldn't get the sound to work. All this after paying for 2 hours in labor charges, I have a PCM with no sound I guess I have to sell this unit to someone with a bose system now. Does this sound right to you guys?

POST 7Original post

I just plugged in my second aftermarket PCM unit and everything works as it was intended. Not only does the unit work but because I have Sport Chrono I now have access to all of the Sport Chrono plus features like DRL and automatic doorlocking and full lap timing. I didn't do a thing other than plug it in. The first obviously came from a car without the sport chrono plus. G.
