Having horrible time with Apple Carplay disconnecting constantly...suspecting it's Porsche not Apple. Are there any sequences of hitting buttons that make it reconnect faster? What is the latest PCM release number and can it be downloaded or requires dealer visit? Much appreciated

@cabncruzr (Welcome to the forum, by the way) : Your experience isn't unique. Porsche's implementation of CarPlay within PCM4 is far from seamless -- which is an oddity considering that it works far better in VW's Infotainment suite, as well as in Dodge's Uconnect (I've experienced both firsthand).

For instance: Mine disconnects on occasion, will not load on occasion, hiccups/freezes on occasion, and will not dim/change color profile to match the interior lights on occasion.

The best things to do are threefold:
  • ALWAYS start the car, then (and only then) connect your phone. That order tends to minimize hiccups.
  • If CarPlay hiccups, unplug the phone at the Lightning connection, plug it back in, and make sure the screen is unlocked even if you have the phone set to unlock when CarPlay is active. Sometimes PCM simply doesn't recognize that 'unlocked' setting, I've found.
  • If CarPlay does not load, you can reboot PCM4 while the car's running or in motion by holding in the volume knob for 20 seconds. (You'll know it's rebooting because you'll see a colored 'Porsche' crest image shown in profile as the first image.) This almost always fixes any immediate issues.
If none of the above work, make sure your iPhone's iOS version is up to date.

Hope this helps!

Mike, thanks for the PCM reset hint.

I don't usually have any problem with CarPlay once the phone is connected as an iPhone. I do occasionally have the phone not be recognized at all, or go away after connecting. I think it is due to a bad, i.e. cheap, USB wire. Next time I have a problem I will try the reset trick.

Sure... come in with a better LOGICAL answer! (n) I was looking like the smart guy for once!

I tried this on my way home from the gym this evening. It's a good trick to know (though I don't typically have trouble with the PCM). Here is what I found. FWIW, I was listening to the radio (Honest! Over-the-air radio!) at the time. My decommissioned iPhone was plugged into the central USB port and actively running CarPlay. My Android phone was in my jacket pocket configured as a WiFi hotspot so that my iPhone could have a WiFi data source.

First the audio stopped as if I'd pushed the button for "Audio Mute" (which of course I had).

After maybe 5 sec the screen went black (as if that is a way to mute the screen - will have to check the Good To Know manual).

I released the button after 12 or 15 seconds, which wasn't the specified 20 sec. The screen and audio stayed off.

Somehow (I don't remember how) I got the screen and audio back. I think I imagine I remember hitting the Volume knob again as if to re-start the audio. Anyway I got it back.

I tried again and this time held the Volume button while I counted seconds. After about 20 sec the Porsche crest did appear! At some point I released the button, don't recall if before or after the crest appeared.

My Android phone was immediately connected via Bluetooth. Maybe 30 or more later the PCM (finally) asked me how it should connect the iPhone! Bingo!

The significance of this is that if I (or you) connect an iPhone in the central USB port and tell the PCM to use it as an iPhone so that I (or you) can run CarPlay, I (or you) lose the Android's Bluetooth link to do phone calls through the audio system. The GTK manual says you can reconfigure it via the Connection Manager but it just reconnects the iPhone again and I (or you) immediately re-lose the Android's Bluetooth link. After resetting the PCM with the Volume button the PCM asks what to do with the iPhone (once it finds it) and I (or you) can select iPod, thereby re-establishing my (or your) Android's link. In other words, it's a way of restoring the Android's phone link while driving. I've been wondering how to do that.

Worth remembering!

Interesting...I've found the Porsche version to be WAY more stable than my other CarPlay unit - a Kenwood DNX893s. I've had it fail to load maybe 3 times the whole time I've owned the car.

My God man....I could kiss you. The few times I couldn't get it to load I would sit there and wait until it turns fully off, and to me this means when the SportChrono clock does to 12. Now I know how to reboot on the rare occasion I might need to...wonderful!

Some great tips thanks guys, my wife’s new mini (bmw) has wireless CarPlay which is way better than wired, a seamless connection when you start the car, but sometimes confuses whose iphone to connect to!
Anyway, if anyone is looking at a wireless upgrade to PCM4, please let us know because I for one would be very interested.

did you try rebooting the PCM and rebooting the phone? I know it sounds silly but it will fix many many things

Wired connection I assume? cable issue and or dirty phone port is what I would be looking at first
To this point...

My SA warned against using third-party usb wires. I had a third-party wire when I picked the car up, and sure enough it kept disconnecting on me. Traded the wire for a gen-u-ine apple wire when I got home and haven’t had a problem since. Though it does take a while to activate when when I turn my car on sometimes.

The quality of third party wires varies, and so does the price. The PCM has proven not to be a stellar performer either... I understand the SA's position, who to blame first? A $3 Chinese made Thunderbolt knock-off or Porsche for its PCM?

I have used two 3d party cables, a 1ft straight one which proved to be too short for me to plug it in comfortably and a 1 ft spiral one which does the job perfectly.

Lest we forget, Porsche sells a spiral one too for $45 or so...

I found that the connection to the phone was the source of my issues with the same symptom (different car). I cleaned out the lightning plug in on my phone (removed lint with wooden toothpick) and problem solved.

Carplay is connected not through the glovebox usb but through the one in the center armrest.

I dont have the usb in the centre armrest only a 12v connection ?? Does this mean i cant connect car play?
I think that's what it means. Having said that, you can supposedly retrofit CarPlay to the car, the PCM is capable of it, and "all" you need to do is buy the software license for CarPlay and have a dealer load it up. I say "all" because I'm wondering where you'd run the usb connection for the carplay, as you obviously don't have one in the center console. That said, I know it's been done, and I've also been told by friends of friends who are either Porsche techs or indy Porsche techs that it can be done. I've also researched this prior to buying my car and a bunch of Macan folks were able to get this done.

You need to buy this: Apple CarPlay - 718 2017+ but look around online, I remember seeing it for roughly $525 elsewhere.

Did you lift the armrest? There is a release button on the passenger side. USB port and phone compartment would be underneath.

718 are only capable of hard-wired CarPlay; so don't waste your time trying to set it up any other way.
Guessing the dealer was incorrect.
Almost 100% sure it's the armrest USB port that does CarPlay. At least that's how it is in my car and other cars whenever the subject matter comes up here.

Porsche's configurator used to say that adding CarPlay would remove the 12v connection and replace it with a USB connection in the armrest; and also for some reason remove the AUX connection in the glovebox. They've changed it now. Now (since 2019 or 2020) when you select "Navigation including Porsche Connect," it says: "USB interface instead of 12-v socket in center console storage compartment. Deletion of AUX interface in the glove compartment." And CarPlay is now (since 2019) a stand-alone option -- which incidentally makes a ton more sense. But anyways, I believe in 2017 and 2018 for you to have CarPlay the car had to come with either Connect, or more likely Connect+ -- although I'm still struggling to figure out the difference between the two.
