Man am I the only one that hates all of these android head units? I much prefer adding the carplay box to the stock head unit. None of these have the same build quality as the OEM equipment and just looks off to me.
What is the current "best" carplay add on box people are using now?

But for those who want to retain the PCM, Android Auto or Carplay can be added with various solutions from Isudar, Mr 12 Volt, JoyeAuto and others. A lot of people like Mr 12 Volt, but that may be because they have the option (in the USA anyway) of having it professionally fitted. Opening the PCM can cut your fingers on the cheap, sharp tin, if you are not careful and fitting the add-on boards is tricky, which is why people like having those units professionally installed. I have had two Isudar boards which worked OK, but I wanted to get away from the dated PCM. Try googling Mr 12 Volt and see if that suits.

My sentiments exactly. It's getting a real, up-to-date infotainment solution that I wanted. Porsche themselves recognise how dated the PCM 3.1 is, which is why they offer a much better solution in the current cars. I didn't really want to drop 100 grand just to get a better infotainment solution, and, as you say, you can get 99% there for a few hundred bucks. No brainer for me.

I had to extend my camera power cable. It's easy enough to add a length of wire and fix with one of the solder connectors you heat up, or even a terminal block.
On your broken tab, do you have the broken bit? Is it worth fixing it rather than returning it? Some epoxy adhesive will create a very strong fix. Also, I think the head unit will be very secure with 3 tabs, so as a worst case option you probably don't need it...

I am sending the unit back so they can send me a replacement. I am just not happy that I can't knock this out during this long 4th of July weekend, and I am not sure when I'll get time again to do this. I might just do all the work to install this unit, ship the unit back, and then swap the new one in when it comes. But then, now I am stuck without the wires for the cameras anyway LOL....

Yes. I temporarily lost one of the 4 screws in the Cayman and ended up installing with just 3. No problem at all. When I finally got a round tuit, I replaced the missing screw with - prepare to be amazed - a genuine Porsche screw. And a few days later of course, I found the missing screw under the seat.

I am looking at the install guide shared in OneDrive and noticed that the backup/front camera installation information doesn't help at all. Can we update that doc with specific information for this CHSTEK unit? There are several camera inputs, CVBA-1, CVBS-2 and CAM-VIN and there's also another AV adapter cable that comes with the kit. Would be nice to know what connects to what, and how to make the camera view pops up in reverse and whats the best cable to tap in for camera power etc.

Did you look at the very end of the guide? There's some unedited content there that needs formatting properly and I can't remember if there is more camera info there.. But we do need to update it for the Chstek
If your car is manual you'll have to search the thread as the installation is a bit more complex, but all the info is there.
If you are PDK then use the CAM VIN RCA and then tap the camera power cable to the brown wire in the harness. Do not try any other power lines, just the brown one. Again there are pics in the thread. Shout if you have any problems..

For manual cars, to install the rear camera, tap into the blue-black wire from the rear body control module located under the left seat. This wire goes hot when reverse is selected.

Hi Martin, I'm afraid you can't use the porsche tpms but the aftermarket units work well, although they don't display info in the multi function display, instead it runs as an app in the head unit. I have set mine to auto start when the head unit boots so it is always running.
The porsche car settings in the MFD still work, for the features that remain. By that I mean the navigation display, radio etc do not work in the MFD as the hardware is in the PCM so gets removed. Most of us use the car settings to hide the screens in the MFD that are no longer relevant.

Well that's my understanding, but I'm very happy to be proven wrong! Your explanation sounds very plausible, does anyone else have a definitive answer on this?
If integrated tpms isn't a deal breaker for a Chstek upgrade then Martin could give it a go and whatever the result we'll add it to the knowledge base..😁

Can someone who has installed the CHSTEK unit verify that the Porsche TPMS still displays in the instrument cluster?
If I don't get an answer to this question I may volunteer to be the guinea pig.
Thanks,
Martin

I believe you are correct. I have a PDF of the PCM3.1 manual and the words "TPMS" and "tire" are not in the manual. The word "tyre" does appear four times but it is used only in relation to the GPS/navigation system. That tells me TPMS is not in the PCM unit.
