Multiecuscan

Hello, I replaced the original Uconnect 5 (Fiat 330 VP2 ECE) in my Fiat 500 L (199) with a Uconnect 5 (Fiat 330 VP2 NAV ECE).

Everything works.

Both radios are from 2013 and have software version VP2_CO_13.00.74.00.

Only the odometer is flashing.

Both radios have the same HEX data stored.

Without NAV:

I changed the HEX of the navigation radio from 40 to C7 in byte 121.

I performed a proxy alignment.

The flashing odometer remains.

What did I do wrong?

Perhaps you can help?

Thank you very much.

Florian

Do you get an error message during proxy allignment?

Good evening, yes, unfortunately. The proxy isn't working. The radio isn't registered with the vehicle. I'll try to insert the pictures here.

After a failed proxy you will see a button here: (see attached file)

Can you upload what you see then?

Hi there, bedankt.

I will perform the proxy alignment again, and if there is a notification with my MES version, I will post it here.

@ abarthmultijet

I think I know what you mean, the report. I completely overlooked it. I'm adding it now. Sorry I have so little experience.

Change Byte 123 from 01 to 11

And let me know how it went.

Hartelijk dank abarthmultijet!

Dat was precies de juiste weg. Groeten aan de provincie Noord-Brabant.
