I should have PCM 4.0 then... To be sure, do the following with key in ignition:

1. Press “CAR” button on PCM

2. Tap/select “SET” located on lower edge of the screen

3. Scroll down to “Software Update” and tap/select

4. Scroll to “Version Information” and tap/select

5. Scroll to bottom to find “Software Version” and "Hardware Version"

6. Record information or grab a photo of the screen

Appreciate all the help as a member sent me th AIO file and I got it all updated and working. So awesome. Great community.

Westcoast

@Ryan Day That's great, enjoy!

Speedopoulos

This is amazing by the way. Huge appreciation for those that have spent time building this for the rest of us! It runs perfectly in my 991.2 Turbo S

Has anyone found a way to change the map in the gauges to AA?

Westcoast

Welcome to the forum!

By "gauges" if you mean in the cluster, no, the map information that is displayed there is only from the OEM NAV program.

Speedopoulos

Awesome, thank you for the warm welcome and confirmation.

If I want to only be able to activate Android Auto in my 991.2 (2018) do I need to download the AIO file for that or the original matching MIB firmware?
My concern is not messing else up. For example, the GT2RS logo that the screen starts up with.
Thank you

I was going to update mine until a friend tried and totally f-uped his PCM. A trip to the dealership and $1500 fixed his PCM.

Westcoast

Then he didn’t follow the instructions... nearly impossible to break the PCM with AIO.

Westcoast

AIO doesn’t change the boot logo... AIO updates the firmware level, and enables both AA and CP. Have you read the OEM Navigation update thread?

Done it on 3 cars so far No issues. Ha the 1st 2 done by a guy and did the 3rd (2018Turbo S) myself.

Are there any files available to just update the firmware for a PCM ? I don’t need AIO, but can’t update navigation maps beyond 2018 because I have old firmware.

mityaz

I think I've read this a bit, but still trying to understand fully.
Can I do all this by just downloading the newest file (the 1.7GB one), unpacking to the root folder of FAT32 SD card, removing the underscore for it to autorun upon insertion, and then running the fix command from the engineering menu? Is that literally it?

If not find this guy @simaservis1108 he is a master on our PCM

Westcoast

Not that I am aware of.

Why wouldn't you want the firmware version to be updated via AIO? This process brings the PCM to the latest release and enables the ability to update the maps to those currently available.
