Update: So its been working great so far, but I wanted wireless android auto so...

I'm a beta tester for AAWireless (AAWireless) , which is basically a USB dongle with bluetooth and wifi built in. So Unichip Android Auto + AAwireless == Wireless Android Auto working perfectly :)

View attachment 28323

Plug the AAWireless device into the USB port, and then just pair to the bluetooth provided by AAWireless, and it connects you to its own builtin wifi automatically, and you're done. nearly lag-less. I do NOT have Porsche Connect (builtin wifi or SIM card slot), FWIW.
You are so lucky to be a beta tester on that. I have been following the development of AAwireless as of late and I can't wait for it to become available. I will buy it in a heartbeat!

Another AAWireless update: You can change the DPI so that the apps give you a different view. Kinda small, but still neat:

That is actually very useful as the map, at least in my opinion, has too much horizontal wasted space.

Yea, I would agree with you. But this ends up being too small for my old bi-focaled eyes to read without straining, and also, the buttons are harder to press since they are smaller. I changed it to use a lower "DPI" (120 fwiw), which gives more vertical height but doesnt split screen it.

I really want AA in my car but the level of security exposure scares me. I get that you can use a burner laptop but what if it is also installing software that compromises your phone when you connect to Android Auto? Hope that's not the case obviously but I can't take the risk.

Just out of curiosity, why does one of the pictures show the side console pulled off?

Then we should hire Unichip for the US Intelligence Community because that would be a very sophisticated piece of software for an extremely limited audience. They can help us overspin the Iranian centrifuges again...

That's a good call out. I previously had a hardware-based solution (Naviplus) - which I'd removed in lieu of Unichip's software-based solution. I didn't fully re-assemble the car until after I know the software-based solution actually worked :) .... just in case I needed to re-install the hardware solution.

Good news is that the Unitech solution works GREAT.

There is no risk involved.
I have done remote activation on one of the member Pantaleoc cars.
You can ask him :)

I apparently have too much time on my hands, wrote an android auto application that talks to Torque Pro to get OBDII information:

Speed+RPM over time, boost level, oil temp, and ambient and IAT temps

self-explanatory

oooooohhhhh - would you be willing to share the APK?
I would :)


Phone needs to be rooted as this is just the type of application that Google doesnt want folks to make, and you need to use https://github.com/Eselter/AA-Phenotype-Patcher to have it show on AA launcher.

And have Torque Pro installed and configured with your bluetooth OBDII reader (I have an OBDLink LX unit and it works great with this and with Harry's Lap Timer)

It also shows a notification when you fuel level gets too low, with an audible 'ding' and a nice lady telling you that you need gas. Tapping the notification brings up Google Maps with 'gas stations near me'.


PM me your email and I'll send it off.

Sorry for the newbie questions, but:

1. How does this affect any over-the-air updates that Porsche releases to the PCM?

2. I think I already know the answer, but would this void the warranty? If so, will it void the entire warranty altogether or just the warranty for the PCM?

Thanks

FWIW... Unichip said that a software update would overwrite their additional module and that they would redo the installation process for up to 1 year after the initial install. So, it specifically wont prevent nor interfere with a PCM update, you'll just lose the functionality until they restore it.

I had this done about three months ago. Bought the stuff from unichip, he connected remotely and happy days; Android Auto working. I didn't think their communication was particuarly good, but everything went perfectly. I used my usual laptop with no additional security. I trusted they had better things to do than breach/destroy my laptop and I was right. It's been perfect and totally made up for Porsche's stupidity in not enabling AA as standard. As I understand it, everything to operate AA is already in place, it's just buried and unavailable.

I'd be interested to know the contents of the SD card. Do the files get erased as part of the install? I'm curious if it's just a configuration file updatw or if there is actually software that is being installed.

There's only about 2MB on content on the SD card. Snapshots of the directory contents attached -- as well as sample contents of one of the config files (aka it's not a readable format like XML). The 3 directories seems to have identical content, but I've not done a diff on the files themselves.

So I have this solution, and what I thought at the time was that they are replacing the certificate authority chain to add in their own self-signed module, and a patched version of the SSL shared libraries (the .so files) to support this. "m1" being the new/replaced trusted module that actually has the AA protocol support, and the pem file is the updated client certificate that reflects the updated cert authority file. The dealer updates do not detect these files, but simply overwrites all of the data within the PCM with the newest image/files.

Mind you, I have no idea how much of this is correct. I'm just a 30+ year computer programmer trying to reverse engineer someone else's solution :)

Also... I was a beta tester for AAWireless, which enables wireless Android Auto, and I just received the final product two days ago, and it works absolutely flawlessly with the unichip solution. I am extremely pleased with the combination.

Dealer can surely detect that via diagnostic tool since VCRN and FAZIT strings will be invalid in diagnostics.They just didnt check.
Without complete instructions these files are completely useless.
