Bytes for Fiat 500 Proxy Alingment

[aam583]

Update: I managed to find the backup file in the MES program. I didn't know MES saved every proxy you do in a text file. I got all the lights to disappear. The only thing I still don't have is the TPMS screen that shows all the pressures; that is still missing but everything else works fine

Could you please share what your current proxy is? I am stuck without the boost gauge...

For the Sport gauge to work properly you need to change byte 49 to C0.
If your 2017 cluster comes from an EU car, there will always be some errors because it's not fully compatible.
If you need help make the Abarth graphics work post your proxy.

Hello everyone,

I have a 2020 Abarth with Uconnect 7, but I can't connect to CarPlay.
I have the following factory settings:

Code: Select all

33 32 31 35 30 30 36 30 37 30 34 4F 55 54 50 55 54 44 4A 49 54 20 20 09 23 4F 04 00 05 10 00 00 00 09 00 00 04 10 00 00 00 81 C7 75 06 F9 00 1C C0 00 00 00 16 00 01 00 94 06 01 01 00 40 00 02 20 75 41 0A 0C 0D 01 80 2E 24 00 00 00 00 31 02 51 00 00 00 04 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 47 00 94 08 52 00 04 88 00 00 20 80 00 00 40 00 85 00 0F 00 00 00 80 05 00 C0 02 00 00 00 00 00 00 00 00 00 00 00 00 00 23 44 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

I modified the bytes
Bytes 121 = 40 (No changing) Navi
Bytes 148 = 05 (At place of 44)
Bytes 157 = 01 (At place of 00 ) Carplay
Bytes 158 = 00 (No changing)
Bytes 159 = 00 (No changing)
Bytes 160 = 01 (At place of 00 ) Android Auto

Code: Select all

But unfortunately, it doesn't work.
The coding is flashed correctly, but CarPlay doesn't work even with the original Apple cable.

Can someone help me?

Hello everyone, I have a 2019 Fiat 500 Lounge with Uconnect 7" and a single USB port. I have tried all the proxy codes I could find to activate Carplay without success. I reverse engineered the bytes but couldn't get it to work.

193 bytes with uconnect on 44 and USB byte 115 on 00. I changed it to 05 01 01 and USB to 04, but without success. When I connect my phone, I have mobile phone display options that appear with iPhone, but when I click on them, nothing happens.

Does anyone have any ideas or could share their proxy code for a Fiat 500 or Abarth with a single USB port?
@Romain did you find a solution ? we have the same uconnect byte 44 and I did not see a lot this byte.

Hello,

unfortunately not all Uconnects 7" have the hardware for the Carplay.

Anyway your best shot is to update the firmware first (link: https://drive.google.com/file/d/1Y4irT-r9_FgREHnCzB6YPCEZ3VQtspgH/view?usp=sharing).
You need to extract all the fies in the root folder of a USB drive formatted in FAT32. After you insert it and wait for 60 seconds, the Uconnect will prompt you to start the update. It takes approx 30 minutes, you better do it while driving or with the battery connected to a charger. DO NOT TURN THE DASH/UCONNECT OFF DURING THE PROCESS.

After the upadte is done, you can try again with the proxy alignment.

You don not have the AUX port, right?

My suggestion is the following version:

Code: Select all
