Multiecuscan

Hello, good evening.
In 2018 i bought (for my wife) a Fiat 500L 1.3 multijet pop star, new.
We are portuguese, living in Portugal.
When i bought it, we waitted for almost 2 months for it. The contract said it would have a uconnect live HD 7 infotainment (no NAV, but carplay and android auto). When we finally got it, the car had a uconnect 5 (the lowest radio at that time, no nav, no carplay, no android auto). I only confirm this 4 or 5 days after, because the seller insisted that we could connect the phone to use navigation (carplay). It didn't. I made a claim that it was not the infotainment mencioned on the contract, demand them to upgrade it... but "Fiat" do not alter original settings. So, they refund part of what i paiyed, the only thing that they could do.
6 years and a couple of months (last November), i saw an “uconnect live 7 HD" on ebay (Italy) and i bought it for a good price).
Seller told me that it should work, it did, but with flashing odometer (km), and when i use reverse i get a black screen, because the car has sensors, but not rear camera). Seller told me that i need to do a proxy alignment. Since the car has a Security Gateway Module, i went to a dealer to do it - but inspite of the car is no longer under warranty, the "new" infotainment and the car itself is my property, "...Fiat does not allow changing original specs of the car". I talked to 6/7 dealerships that they told me that they could do it, but Fiat could penalty them for that.
So i shearched for people that could do it, i found a guy that did that job. He did it, but after that, no more flashing miles or rear camera image, but also no carplay nor android auto... He told me that it was necessary to alter some values to proxy to enable that, and told me that he will contact me... and he desappeared. Never heard a word from him again, neigther answered my calls.
Plan B: read a lot about it, spent the money on a second hand kit with multiecuscan 4.8 (more than enought version for my car), obd cable, colored obd extentions and a bypass to the SGM module. I spent hours findding the SGM module, finally did it and plugged it in, changed the byte 157 and 160 to "01". Since i have 235 hexidecimal places, i changed nothing more.
I find it odd to see that on CAN Setup / Proxy Alignment Procedure /adjustments, it said "Engine type = Gasoline" (it is a diesel 1.3 multijet), but since everything worked, i didn't bother.I did a copy of the proxy values before i changed the values. Afther that i did the proxy alignment and... carplay still not worked.
I picked up a 500L proxy values that i saw on this forum (people just put it here with no specs of the car), paste it on adjustments, did a proxy alignment again... and now i have carplay, but a warning about tire presure sensor off (my car does not have TPMS), power sterring problem and something about fog lights or headlights (my car does not have front fog lights, could it be that?), and get the black screen again, when i put it in reverse gear again. The car works, of course, but i need to solve this. Sorry for my big "testament" but i thought that some context would be necessary.
I do not know the meaning of all the hexidecimal values.

My original proxy values are (original after that dude did the proxy alignment the first time, do not know if it was the same before):

Original:

On this i tried to change byte 157 and 160 to "01", but nothing happened.

This was the one i put after on my car:

I gess the best to do is to use the original one to change, paste and do the proxy alignment, but i need some help...
Thanks guys... HELP!!!

Hi,

Don't just put somebody else proxy in your car.

Best is to put the original proxy code back.

Do you have the app on the home screen called LIVE?

I have.

Press it, and on the left side of the screen you will find a toothed gear, if you press it you can find the uconnect live version code

Uconnect LIVE 8.10.2
Update Manager 6.2.0

Try this one:

33 31 33 33 30 30 34 31 32 34 36 4F 55 54 50 55 54 2D 53 49 54 20 17 11 15 4F 0C 00 05 10 00 00 00 09 04 00 05 10 00 00 00 A7 C7 71 07 85 00 37 00 30 A0 44 06 00 07 08 8C 03 15 01 28 C2 00 D1 02 35 41 0A 0C 0D 00 80 3E 58 00 02 00 00 43 20 29 03 08 11 16 00 86 20 05 05 00 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 CB 00 01 08 0E 00 04 80 10 00 10 80 00 01 40 10 D5 00 11 00 00 49 00 01 14 40 00 00 00 00 00 00 00 20 00 00 00 00 00 00 00 05 00 00 00 00 00 00 00 00 01 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 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 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 00 00 00 00 00 00 00 00 00 00 00 80

Thank you. I Will try it. But I have a question:
This “proxy values” you gave me is almost identical has the one i took, not has identical has my original one.
The difference is;

Byte 125 (you gave me the value D5
Byte 160 (this is for Android auto, right?)
Byte 235 (you gave 80)

Shouldn’t the values be more identical to my original one than the Mod one? Is this right?

I tried it. I have “instrument panel (IPC/NQS) EOL Failed, and automatic transmission (TCM/NCA/NCR) removed.
Also, same blinking km, steering whell error and headlights…

And if you put back the original code? No errors?

I upload original code back, except byte 157 (00 to 01), byte 160 (00 to 01) and byte 250 (00 to 80). No errors, no blinking km, but also, no CarPlay… Please, advise… Thanks.

Edit: I have an aux+USB Port.
