Default free - easy - PCM 5 full screen CarPlay

A little background: I'm a software engineer who bought a Macan with PCM 5 a couple of months ago. I was annoyed seeing all of the vendors taking advantage of the community and charging ridiculous amounts for CarPlay mods. So, I did some reverse engineering on my Macan, made this open-source mod kit for the community and made some CarPlay mods for it.

Recently, other model owners (992, Cayenne) have tested the CarPlay mod to be working so I am trying to share it with those communities! (if someone with a Panamera or 718 can confirm it works - that would be great too!)

Link to instructions and downloads: MH2p SD ModKit
All you need is a computer and an SD card or flash drive that can plug into your vehicle!

This is applicable for 992s from 2019-2022(?). After that they have PCM 6 which already includes full screen CarPlay!

What this does:
changes OEM CarPlay:


to either
"windowed" full screen:


or "true" full screen:


Let me know if you have any questions!

No problem! There are a lot more details about it in my thread on Macan Forum. And the Macan thread here already has users mailing each other an SD card with the mod on it!

>> I was annoyed seeing all of the vendors taking advantage of the community and charging ridiculous amounts for CarPlay mods.

Thanks for 'open sourcing' this, that's awesome. One nit: clearly not everyone has the skills/interest/ability (or even a windows laptop) to make these mods themselves and are happy to pay for an upgrade, so no reason to disparage enterprising vendors 'making a buck'. I mean, Porsche charges $400 bucks an oil change for a trivial mechanical operation and ppl happily pay for that... right?

Got any other tricks up your sleeve?

ps. Full disclosure: I have InnovativeSoft's full screen upgrade (a board sponsor) and love it, so I'm a happy customer.

I have a problem with charging $300 for uploading a couple line software change to your car's PCM; even if the vendor is performing the service themselves, it takes ~10 minutes. I also highly doubt 99% of the vendors selling the modification created it themselves (so they have no R&D costs to subsidize). Free versions have been floating around for a while; they were just hard to find and relatively difficult to install.

I have even more of a problem with vendors selling bootleg activations of features that can be legitimately activated by Porsche. Either activate it for free with the mindset of "I own the car, I can mess with the software" or activate it legitimately.



I do have more mod ideas for the future!

Exactly: I'm 'in software' myself, yet two years ago there certainly wasn't broad awareness of this technique, so I was fine paying for it. Isn't this the arc of progress in a nutshell: what was once obscure/ 'expensive' knowledge is now cheaper for the masses? And thanks to your clever packaging (bravo) it's now a consumer grade solution, so win for all, but again, but why disparage ppl trying to 'just trying make a buck'?

Looking forward to your other ideas... I'd love to make Carplay split screen more useful - like having Waze on the left, and and a larger more useful version of Spotify on the right.... keep the hits comin'.

Regards

I am in the U.K. and found this on the macan thread.

I did my 2021 992 turbo s and 2019 Cayenne today.

if anyone is in the U.K. ( south London / Surrey ) they are welcome to come over and use the SD card.

full screen on the cayenne is nice but on the 992 it is great as the screen is ( or seems ) smaller and harder to see.

If anyone is willing to share their Sd card for a 2023 Macan, I will happily pay for shipping both ways along with any reasonable fee for your troubles

setting up the card takes about 30 min on a Mac. The only issue is deleting hidden files. I assume it is faster on windows.

If someone did the hard reverse engineering work and wanted to sell their solution, good for them. When I see a lot of “vendors” all over forums, Facebook, etc. lying/obscuring what’s actually going on and selling their “services” (using the free tools that have non-commercial licenses) over WhatsApp/Telegram, I have a problem.

Unfortunately, there is no modifying the CarPlay content from the vehicle-side. You’d need a jailbroken iPhone and some custom code on the phone to do that.

The source code is there for you (or anyone else) to read through! That’s the beauty of open source.

What people are buying from vendors is not open source and they are placing complete trust in that vendor they buy from.

Love it! I don't need it (have PCM 6) however, total respect to whoever shares their research for the greater good of consumers (Linux! , Bitcoin!)

Thanks again!

Thanks! I'd be curious to see if a similar/the same method works on PCM 6. No idea what people would want to use it to mod on PCM 6 though.
