SMEG Update
Hello,
I've bought recently (yesterday actually) a 2017 Citroen Grand Picasso 2. Since I know a little about the car for the time being I started with the infotainment.
I've read the topic a bit so I know that there are some issues with certs, I haven't tried to update the Head Unit (or whatever it is called in PSA nomenclature), but I would very much like to do so.
So I figure that my radio is SMEG with navi (at least it seems so from the vin report that I have) the SW version I have is 5.15.29.42-r0 and maps are 20.0.0-r0 (I don't really care about the maps).
I would like to know if there are any chances that you could help me to update the unit (or at least try if the certs are dead).
The "why" is that I would like to see if it is possible to use android auto with the unit with newer SW, the unit already exhibits a screen with CarPlay icon in the background so I reckon there is a glimmer of hope there (I've searched the Net about the topic, but there is a plethora of yup it will work vs. nah it wont...)
So I kindly request your assistance. My VIN is VF7**************[VIN obfuscated, can be read by forum staff]
Also I've noticed that the Citroen update tool is no more is this the case or this is something temporary?
Either way thanks for even reading this =]

Re: SMEG Update
I've moved this out of the NAC RCC Forum as you have a SMEG system. We don't provide updates for this system, sorry. Navigation updates are available from Citroen directly.

I'm pretty sure that the SMEG+ system doesn't have the hardware for Android Auto regardless of firmware fitted.
I'll send you PM shortly.

You have a Nac Wave 2 system, it can be updated, there are no problems with the certificates.

Re: SMEG Update
This not returning anything for the VIN under NAC / RCC systems. It's a very old firmware, but neither of my systems are returning anything under NAC. It seems you have a SMEG system NOT a NAC as suggested above.... and confirmed by Citroen when entering your VIN here:

Re: SMEG Update
Hi sorry for late response I had a bit of work with bureaucracy concerning the car today.
So yes as I originally mentioned I thought I had a SMEG, but the SW version got me really confused, as it was reported by someone in that NAC post.
Either way thanks for taking care of the mess I made
just to clarify this HU that I have it is SMEG or SMEG+ or would it be plainly stated as SMEG+ in the vin report?

But it does have the CarPlay right? I can clearly see the logo on one of the screens.Paul-R wrote: 31 Mar 2025, 13:13 I'm pretty sure that the SMEG+ system doesn't have the hardware for Android Auto regardless of firmware fitted.

Re: SMEG Update
Yes a SMEG unit if you have this on your build sheet. If you can see CarPlay it should already be enabled, but too early for Android Auto (which replaced Mirror Link). Mirror Link is now almost defunct and no longer supported.
Make sure you connect your iPhone to the vehicle with a proper decent cable (preferably with a Apple original cable), as some cheaper cables are not up to the job and some do not support data transfer only charging which can be another reason in case it does not work.

Re: SMEG Update
Maybe it is not the original system of the car.
Firmware 5.15.29.42-r0 (No Android Auto support) and maps 20.0.0-r0 installed, are for Nac Wave 2.

Re: SMEG Update
Of course, that is a possibility if it has been replaced by a previous owner, but we can only go by the VIN - which states SMEG.

Re: SMEG Update
Ok did a quick search throught the papers I've received and indeed it has been replaced in 2020 (9th of september to be precise) the part numbers are 9825029380 1617301680 first is a display it seems the second one is more tricky as google doesnt really show this decisively as a HU.
So if this was the case then if I'm not mistaken one of you guys wrote that wave2 should be ok for update, right? With one of the SW packages from the NAC thread (without lic key, wifi should be fine)?
Thanks !

Re: SMEG Update
No, this is not necessarily the case.
I suspect a dealership would not have replaced this, as they would only replace like for like. So if you can confirm that this has been replaced by the previous owner himself or by a third-party first of all that would help.
This being the case, the updates for the NAC units are tied to the VIN of the vehicle and the original equipment it was fitted with.
This may explain why there are no updates coming up for the VIN you have provided when I enter into the system. So you will likely have to stick with the version you have already, as any updates won’t be authorised being that it is not recognised as the original head unit for the vehicle you have.
In other words, the NAC unit that was used as a donor, had the earliest original firmware installed. It was never updated or there were no further updates at the time it was installed in your vehicle. So this is why it will be stuck on the original firmware it had and you can’t update it with any later version as it stands because they will not be authorised.

Re: SMEG Update
Now I'm a bit more confused, I noticed that the vin on that invoice is different, and written in marker
beauty of second-hand cars...
Edit:
I've actually double checked that it was a replacement from a third party insurance, it took place 3 years in car's life (in 2020), And it's first owner's name there and car brand and such, and the invoices I have with that persons' name are actually exhibiting my vin i.e. authorised Citroen workshop etc. So I guess someone got creative, but that's just to clarify things
Either way if you guys are willing, tell me please which update in theory should work if the HU is in fact a NAC and it was somehow swapped and in some way coded that it should work with the car.
I will just give it a go and see what happens.
I'm completely new to this ecosystem, although OVIP brings some memories from my regular job.
So basically to recap this a bit:
Since the sw version is what it is, and there is carplay in the radio it has to be NAC and Tomas1 stated that this should be wave2, so in theory any SW for NAC wave2 should in theory work?
I don't know if the updates are multi brand updates, i.e. for the whole PSA group or does the Citroen require special updates, Peugot another set of updates for NAC wave2 and so on
Thanks for leaning on this guys much appreciated.
EDIT:
I took the SWL from here https://sites.google.com/view/nac-rcc/system/nac/wave-2
the version was 5.15.37.32-r0 and I got update is not compatible with the system
So is there anything you could help with this?
Can the firmware be at all updated with DiagBox? Or what about the Authorized workshop/dealer?
Or am I stuck with this version and there is really nothing that can be done about it?

Re: SMEG Update
No!
Let me explain again…. It looks like we've established that your unit was replaced with a wave 2 NAC unit at some point.
If your head unit was from a donor vehicle then it would have been coded with the VIN from the donor vehicle and that means any firmware updates will be locked to the original donor vehicle’s VIN. As your vehicle would have a different VIN coded in the BSI, you will not be able to update the head unit as it will not authorise it.
As I explained in my last post, that will likely be why when I input your vehicle VIN into the system, nothing is being returned, as the VIN for your vehicle is stating that it should have a SMEG unit as originally fitted, so will not provide any updates as it is not a NAC unit.
So as I said you are stuck with the firmware that was last updated in the Head Unit as it left the factory or was updated to in the previous vehicle if it was from a donor vehicle.

Re: SMEG Update
Sorry I'm very grateful for your help, but the thing is the HU has to be already signed with a proper vin, otherwise there would be some inconsistencies and a beep/chime that would notify that exact fact (as far as I read on on this topic).GiveMeABreak wrote: 01 Apr 2025, 11:15 No!

When I get diagbox sorted out I can check what is the vin in the HU (I guess it should be readable) or I will get the arduino workaround and see what it does. Because as far as I am reading people do swap HUs and talk about updating like it should work. I know I wont get updates by my vin alone
So that why I'm asking so much about it (that is besides being green in PSA stuff

Re: SMEG Update
So you’ll need to search for Macslavko here as he has done a conversion and can maybe help but we don’t cover this sort of upgrade here.
