if unit is 2nd hand with already activated aa/acp and prepared for your VIN, then if your audio config is similar (was with or without amp vs last proxi on this unit), and when you change USB hub to compatible, then even radio will work fine (sound) and aa/acp will start OK. Otherwise you do proxi 3 bytes mods (e.g. with MES/AlfaOBD), and it works. Then no need of dealer/witech.

 

Thanks, if unit is new without VIN attached would witech then be required to set the appropriate VIN

 

so you do proxi run, can be done with MES/AlfaOBD the same as with Witech. VIN writes in after some time of driving (won't tell you tens miles or so?) MES/AlfaOBD you need if you need to change config e.g. adding aa/acp/nav. witech (or e.g. Autel) you need once you have added aa/acp proxi mods, run proxi but need to activate aa/acp. order matters!!!

 

Thanks Epsonix,

To confirm order to add new hardware without new features (ie no nav or as/ap) I would install new head unit, use MES and cable to perform proxi alignment and should be good to go.

only need witech if I use MES to write the three bits to add as/ap.

do I understand correctly

thanks again

Len

 

yes, if no need currently to activate you just run proxi, but no harm to prepare already headunit so modify 3 bytes for aa/acp.

only when you need to add aa/acp it is must to setup 3 bytes for it, change usb hub and do proxi, after you go to autel or witech to activate aa/acp.

 

Thanks epsonix

 

Buy a used one with CP AA already active, I can write your vin and just so proxi aligment with 3 bytes.. But i’m in italy

 

Is there a way to tell if used unit has as/ap active? Would all 2019 units have it active?

I assume would ship unit to you to write VIN

Thanks

Len

 

If you know plate or vin number can check for optional list .. or need to ask to user that selling this unit. I can know if already active only when read in bench mode

 

Hello all!
I need to activate AA in a my19 Giulia I recently bought used. It has single USB port.

Here's the data:

Alfa Romeo Giulia 2.2Mjet 160 CV my19 (first sold in 2020)

ETM (Entertainment Telematic Module)
ISO Code:
00 24 70 4E 17
Hardware number:
50355176021 - Ver: 02
Software number:
50455007755 - Ver: 0005

Software version: MV-090.000.061

Here are the proxy bytes values recalled in this thread:
115: 12
157: 34
161: 03
163: 1A
174: 00

I don't use Apple phones, so if a USB port change would needed just for Apple car I will keep mine.

Could you help me to start the correct procedure?
What byte values to change?
I'm sure no modification was made before. Is still Witech needed in MY19 version? Could BrainBee diagnostic (a car mechanic I know has it) do the job?

Thanks

 

Vorrei fare la stessa cosa anch'io, la versione di software è la stessa su stelvio agosto 2018, a chi posso chiedere per avere delle informazioni?

 

Hello buteo i see italian flag so please write me in pm

 

So i cant find a TLDR for this anywhere. I see the guide on how to activate. How do i know what version radio module I have?

 

How do i know what version radio module I have?

As explained in the previous posts, just check the software version from Infotainment menu

 

Thats what I thought I read, but im a guy who needs direct clarification. .056... + is guaranteed version 2. Thanks

 

Always avaiable used, HIGH version with AA / CP unlocked . I send already written with your vin so no pin code request . If interested please PM me . I can send you some pics on bench and Multiecuscan screen report
