No change. I finally solved it inadvertently when I replaced my car battery with one that had higher cold cranking AMPs ( IIRC, stock had ~600 CCA and I installed an AGM with ~900 CCA).

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 decided the time had come to replace the aging non- BOSE CDR30 in my 2010 987.2 Cayman with something more modern. As an iPhone user, I wanted Apple CarPlay , but I didn’t want to lock myself in, so I wanted a head unit which also supported Android Auto . I chose the Sony XAV-AV100 , primarily because of it’s understated styling. I purchased a Quadlock CANbus adapter which promised, “ plug and play installation”, unfortunately this wasn’t quite the case. The new head unit started up OK, but no sound was coming out of the speakers... The Quadlock adapter only provided wiring for Block A of the Quadlock, leaving Block B and C unwired. According to this wiring diagram , Block B only has one pin, and Block C should have four. On my car, Block B has five... ( w hite, red/white, yellow, black, and blue). I reconnected the CDR30 and checked the voltage on the pins of Block B on the back on the head unit. The only pin reading voltage was the blue one (8v). I turned the head unit on and retested the pins. Both the white and red/white pins now read 12v, and the blue pin continued to read 8v. I reconnected the Sony head unit and connected the Block B white and red/white pins to the blue/white REM OUT pin on the back of the head unit. Everything worked! Having spent the best part of six hours on this it was time to call it a day. Tomorrow I’ll be trying to see if I can use the car’s built in microphone rather than the supplied external one. Block C looks like AUX, so I’m assuming the mic must be the yellow and black pins in Block B. Does anyone know what the 8v blue pin in Block B is powering? As an aside, the CDR30 can be turned on without the keys on the ignition, this isn’t the case with the Sony. Further, if you have the keys in the ignition and turn on the Sony, upon starting the engine the Sony will reboot. Is this expected behaviour? Nathan

POST 2Original post

I replaced my CDR30 with a Pioneer over 8 yrs ago, so I'm kinda rusty on the quadlock adapter. Also, I have a base 987-2 without SPP, so I have a simpler conversion. According to my old documentation, Block B is all speaker leads, so you shouldn't be providing any voltage there. But there is a blue block with only one (red/white) wire that is to provide +12V to an external amplifier.. Maybe just a trigger to tell it to turn-on. I believe with most aftermarket head units you give-up the ability to run the headunit without the ignition On. The stock unit harness has a constant +12V and gets on/off signals over Canbus, whereas aftermarket units require a switched +12V signal (wired to an ignition switched fuse) as a trigger to turn on/off. I had that reboot issue for years. t is obviously caused by a voltage drop when the starter runs. I tried a dedicated circuit directly wired to the battery. No change. I finally solved it inadvertently when I replaced my car battery with one that had higher cold cranking AMPs ( IIRC, stock had ~600 CCA and I installed an AGM with ~900 CCA). That solution has held for a couple years. Now I can leave the head unit/NAV/music running while topping-up gas or sitting in the car waiting while the wife is shopping, and it stays running when I restart the engine.

POST 3Original post

Thanks for the reply. Good to know that that most aftermarket head units can’t be run without the keys in the ignition. The Block B I’m referring to is the blue block, only mine has five pins... After further investigation, the blue 8v pin turns on with the stereo and off a few mins after the stereo is powered off. With just the red/white pin connected to 12v everything appears to work fine. I have no idea what the white 12v and blue 8v pins are powering... Perhaps something to do with the telephone? I find it hard to believe it would be powering any non communication devices. I checked the voltage on the switched live when starting the engine and it drops to almost zero for a few seconds. As you said, this obviously explains the reboot. I didn’t have any luck hooking in to the built in microphone. I’m using an additional mic for now (mounted on the shelf underneath the steering wheel) but I might revisit this in the future. Nathan

POST 4Original post

Nathan, did you have any luck keeping the OEM microphone?

POST 5Original post

I didn't, but to be honest I'm quite happy with the placement underneath the steering wheel.
