987.2 Cayman interior power sockets - switched?
Discussion
Hi all. Recently acquired a nice 987.2 Cayman S
Just sorting audio/iPhone mount and have a question about the two interior power sockets. 1 used feed in armrest and one in passenger footwell.
Does these turn off after x minutes after car turned off? Concerned that leaving iPod plugged in would drain battery.
Same question for passenger footwell as will either leave connected charged iPhone air vent mount and/or dash cam.
Thanks!

Thanks, is that the same for both or just the footwell one?
I wonder if it can me modified to be switched only though?….
Yes, and yes. They are both on the same fuse and if you can find a switched power source to tap in the fuse panel then making the accessories circuit switched takes a few minutes (Google "Add a Circuit Piggy Back Mini Blade Fuse Tap" and add a spade connector on the end of the red wire).I wonder if it can me modified to be switched only though?….
Thanks, something to consider.
The footwell one I will have charger (ESR Halolock) for phone mount and charge. Maybe dash cam but if issue I can always hardwire that the normal way.
In the armrest, I will have Porsche iPod link cable (with old iPod Classic left in) and usb splitter to power that and a bluetooth receiver so I can stream podcasts/etc. from iPhone.
I suspect the footwell one won't drain (as no phone left in overnight in to draw any current).
The armrest one however will keep the bluetooth receiver and iPod Classic charged/in use I assume so would draw current when car is locked. Whether that will draw anywhere near enough to be an issue I don't know. Can unplug each time, or make it switches as per your suggestion (which I assume would affect footwell one as well as anything else on that circuit? not sure if there is anything?).

Sooner or later you’ll flatten the battery if you leave them plugged in. It doesn’t take much to flatten Porsche batteries, in my experience.
There’s nothing else on that circuit as far as I can remember. I think it’s actually called the accessory socket circuit, or something similar.

A possible update of sorts.
Went to Porsche to pickup iPod cable, and asked about the ports so parts guy got an experienced tech out (wasn't a junior!).
The 12V are always on (footwell and cig lighter)
USB - the tech was "pretty sure" turned off after a while (top of his head about 30m or so) and the port direct to PCM so basically when the PCM shuts down (stays awake for a while as it takes time to boot up so left on if you're only stopping for a short while, filling up etc.)
So, to test this. I have a USB Bluetooth receiver (which I will use for streaming from iPhone) plugged in. This, handily, flashes/lights up. So left for 20m and came back and light off and iPhone could not connect to it.
Open car and ignition on and it wakes up.
Turn car off and stays one but only for a minute or so.
Will check some more (basically if iPod classic I also have plugged in) isn't more charged up when I next go in, then it's also not getting power either (coming from same USB using a splitter).
So could be a bit of a result! iPod classic that I can use/navigate using the PCM, and streaming to iPhone for Apple Music/Podcasts etc. and no need to unplug every time I lock the car up......

Apologies: I took it from this that you were using the (unswitched) armrest/ash tray socket to provide USB power. It's absolutely correct to say that the USB power from your head unit is switched (after a delay). It doesn't provide a lot of current but possibly enough for what you are proposing.Just FYI but I found that if you use both the 3.5mm socket & the 30-pin adapter at the same time you can get some weird stuff happening with the volume (I seem to recall that the iPod was badly attenuated) but it could have been down to the bluetooth adapter I was using. Worth checking though.
