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?
