Re: Bytes for Fiat 500 Proxy Alingment

Post by ninjaturtle003 »

Hi all,

First of all I've been reading the forum for a few weeks, it's super interesting and well documented :)

As many on this thread, I updated our Fiat 500 1.2 8V (start & stop, rear radar) from 2019 from a 5'" to UConnect 7 Display. I followed the information provided on the forum, ran a proxy alignment, the odometer do not flash anymore, all commands works fine, except CarPlay doesnt start on the Uconnect 7.

Before i ran the proxy alignment the carplay worked fine, but once I flashed the ECU, the Carplay didnt work anymore. The phone when plugged into the car switch to CarPlay, but nothing happen on the U Connect screen.

Byte 148 (1 USB): only works at 05 for me, evenif when i first ran the proxy alignment it said to switch to 5C, but then 'out of range' message.

Byte 148 (UConnect7): 05

Byte 157(CarPlay): 01

Byte 160 (Android Auto): 01

My proxy configuration is the following right now:

33 32 31 35 30 30 34 30 30 32 38 4F 55 54 50 55 54 44 4A 49 54 20 18 06

I'd be taking any help/advice :)
