RT6 to NAC (Connected NAV) Upgrade

[SpiralDragon]

If you have RT6 sat-nav system you need to install speed cam file (updated monthly). The same goes for SMEG touchscreen head units.
If you have NAC touchscreen head unit, you’ll need Connected Services subscription in order to get speed cam alerts.

Have installed Nac. Speeds show but not speed cameras.

Speed limits are shown on the maps - but not cameras - you have your answer you'll only get these via a subscription if this a factory-fitted NAC and not an upgrade as the connected services are ties to the vehicle VIN.

Hey guys!

Super helpful thread here, I finished reading through and I still have some concerns with my case, so let me lay out my plan and maybe you can confirm if it can work or point out what I missed.

Status Quo
I have a Peugeot 3008 Mk1 (2010) with RNEG RT4 headunit and the (in)famous motorized screen on the top of the dashboard.

My goal
I'd like to use Android Auto keeping the OEM look & feel as much as possible: using the built in screen, using the factory JBL system, using the controls (stalk behind the steering wheel).
I saw something similar in this Peugeot RCZ NAC upgrade video.

Questions
As far as I understand from this thread, RT6 to NAC is absolutely possible and that would get me to OEM Android Auto / CarPlay support, but I still have some questions / concerns:

Q1: since RT4 to RT6 is plug&play, RT4 to NAC should be the same as described here with the pre-made adapter cables from AliExpress right?
Q2: my RT4 has the controls on this 1 DIN unit. Will I loose the functionality of these in favor of the 7" touch screen?

Q3: will this old stalk work with NAC? I don't have other steering wheel controls sadly.

Q4: do I get it right that the NAC HU is not a regular DIN size and I probably need to modify the frame of the NAC unit?

Q5: I'm not sure if the RT4/6 and the NAC display is just swappable on this motorized container or also needs modification on it's frame?
Q6: will the NAC HU recognize / support all the vehicle settings I have currently specific to my car (light settings, heads-up-display, etc)?

Thanks a lot!

You don't have an RT4! That's a MyWay system.....

Again - another one of those videos where the person has left no information, no links as to what he had to do......

If your architecture is compatible (you have a CAN2004 architecture), it will involve for sure new harnesses, new screen, arduino and diagbox configuration. I can't help you with this at all. Some of the conversion here were for DS5s, that at least had CAN2010 architecture.

In addition to what Marc said above (all correct), I'll add up some details:
You'd probabbly need a CAN2010 converter first. Then the wire harness, NAC head unit and new screen.

Status Quo
I have a Peugeot 3008 Mk1 (2010) with RNEG RT4 headunit and the (in)famous motorized screen on the top of the dashboard.

You have a Harman-Becker's RNEG head unit (not a MagnetiMarelli's RT4). So, no comparisson with RT4/6 as it's completly different headunit.

My goal
I'd like to use Android Auto keeping the OEM look & feel as much as possible: using the built in screen, using the factory JBL system, using the controls (stalk behind the steering wheel).
With NAC you'd have to use DGT7C (capacitive) touchscreen. Obviously, it would require some frame modifications...

I saw something similar in this Peugeot RCZ NAC upgrade video.
This is an add-on box that emulates CarPlay with RT6 head unit. Haven't seen one that does the same with RNEG...

Questions
As far as I understand from this thread, RT6 to NAC is absolutely possible and that would get me to OEM Android Auto / CarPlay support, but I still have some questions / concerns:
Yes, but NAC has to be configured to a speciffic car (that was equipped with NAC from factory). In a Peugeot 3008 Mk1 (2010) it was never fitted so there's no configuration file for NAC in that vehicle. You'd need to load a similar car's configuration (maybe 308), hopeing that it's close to your car's functions... It's a hit & miss process so you could load configurations untill you come up to the one that suits your car's functions (buttons et cetera) the best. Again, it may be lacking support for a certain buttons or functions. But JBL can be configured in NAC so that part will work. Needless to say you'd have to work with Arduino NAC software with an Arduino UNO boar + a CANBUS shield. For some parts probably Diagbox with Lexia cable would be needed as well.

Q1: since RT4 to RT6 is plug&play, RT4 to NAC should be the same as described here with the pre-made adapter cables from AliExpress right?
Yes

Q2: my RT4 has the controls on this 1 DIN unit. Will I loose the functionality of these in favor of the 7" touch screen?
Yes. You'd loose those controls as that unit goes out and NAC goes in. Now; NAC doesn't have a DIN1 fascia so no controls there. Everything is transferred to the touchscreen, which in a 3008 (MK1, 2010) is quit far to reach...
Also, you'd need something custom made to cover that NAC front side. It has a black spot to communicate with front fasca in vehicles where fitted (ie volume button and so on), so it might be an error on Diagbox log, but I think it would't prevent it from operating normally (given that you'd be able to controll it via the stalk under the steering wheel)...

Q3: will this old stalk work with NAC? I don't have other steering wheel controls sadly.
It depends... You'd have to investigate which COM unit is that. NAC works with a lot of them due to a veriaty of vehicles being insalled in, so you might be lucky and select one in Arduino that works with NAC.

Q4: do I get it right that the NAC HU is not a regular DIN size and I probably need to modify the frame of the NAC unit?
It's a regular DIN size as it sits perfecly well in the place where SMEG unit or an RT6 was (RNEG is the same size).

Q5: I'm not sure if the RT4/6 and the NAC display is just swappable on this motorized container or also needs modification on it's frame?
As mentioned above, you'd definitelly need to do some frame modiffications for the new screen (fixing points aren't the same). Also, I'm not sure what triggers the display to fold up (BSI or head unit). If that signal comes from BSI (as in the another, RT6 video with CarPlay dongle), then it will automatically fold up and down when you turn on/off the engine. Inclined to beleive that is the case, but I can't garantee that...

Q6: will the NAC HU recognize / support all the vehicle settings I have currently specific to my car (light settings, heads-up-display, etc)?
Again, that is a question of calibration/configuration. I suppose you'd find one that works with most (and meybe even all) the functions you now have (HUD, lights, rain sensor, parking sensors and so on)...

As you can see; there's a lot of unknown areas here and you'd have to work that way mostly on your own, as it's uncharted teritory so far and no-one can give you straight answers for most of your questions...

Thanks a lot!

Thanks Mac - I was hoping you'd chip in here with the details.

Been thinking on this project of yours the whole day. And came up with a big No-go because of the lack of fascia/buttons for the NAC you thought about installing.
It's not just the media buttons you'd need (those under the steering wheel would probabllly work), but you'd also need others: Drive (Car), NAV, Media, Tel, Web (Apps), Clim and most important Setup button. Without those buttons you can't enter into those mods/areas and NAC would be barelly usefull. And it's not on the touchscreen to envoke any of those areas, but outside of it: on the fascia or on black pannels on both sides of touchscreen...

I think your best bet is to get CarPlay and AndroidAuto would be swapping the RNEG for RT6 (also obsolete now) and adding the emulator box as per the video...

[MacSlavko]

Have a look at this one: https://www.aliexpress.com/item/1005002795768900.html. Different versions work with NAC, SMEG and your RNEG.

Hey @Mac and @Marc!

Thanks a LOT for all the details and well, I think you're right: it's a big NO-go.
The CAN2004 - 2010 diff I was not aware of, neither the RNEG / RT difference, that actually surprised me the most. Because every forum I saw the RNEG/RT4 and RNEG2/RT6 seemed to me like synonyms.

All in all the RNEG to RT6 upgrade is the most I could go with virtually no hassle as far as I understand.

However @Mac, the EBILAEN box that you linked is actually the only one on the market right now that makes AA/CP available without completely replacing the HU with a full Android solution - that I don't want. I contacted them already because based on other forum posts currently the RNEG/RNEG2 buttons are not fully supported. Strangely, there's no way to "OK" / accept things. Also strangely, the AliExpress seller actually replied to me and they said they bought an RNEG unit so they can map the buttons, so I put the topic on hold for the time being and I'll see how it goes on their side.

Thanks again for the support, it's really nice to see such a vibrant community.

Cheers!

RT4/5

MyWay / WIPNAV / RNEG

(Note these look identical to the RT6 below, but have an SD card on the front to make it easier to identify)

eMyWay / RT6 / WIPNAV+ / RNEG2

These are the standard head unit designs, but they can also be integrated into the fascia panel (like a DS 5) so that all the controls are incorporated into the fascia and / or use a remote rotary jogger control on the centre console as examples.

[pastabar]

The RNEG/RNEG2 I was aware of, even spotted the ESC vs Back arrow difference

[Para25]

Sorry to piggyback into this topic, I've done the upgrade on my 2013 508sw. Like others the connected services doesn't work. I have the doner vin but feel the services weren't subscribed on the doner vehicle. Reading the threads, am I right in that it has something to do with secured bsi and the vin number is not changeable? Only upgraded as wanted live traffic etc and would be interested if there's a work round.

[GiveMeABreak]

You can't have it both ways.

The Head Unit has to be coded to the vehicle to work correctly. The VIN determines any services the vehicle is entitled to - but Live Services like Traffic is a subscription service and requires the VIN. So there's your problem - if you put the original VIN in of the car - you won't be eligible as your vehicle won't have had this equipment. Secondly the system requires authorisation for live services to work and without the subscription the unit will not provide these....

[Para25]

Thanks Marc, I have full functionality with the unit as it's now coded to my vin other than live services. I was under the impression from various sources that the nac unit also has the original vin embedded and a unique identifiers that ain't changeable and these are recognised by psa servers. From what you say, that then is false and it also has nothing to do with secured bsi?

[MacSlavko]

If Connected Services weren't activated whilst unit was in original vehicle, then it's hard to activate them later with that NAC in another car due to secured BSI, as you mentioned.
Both VINs on BSI and NAC need to match in order to activate Services. At any later point perhaps it can be done with another BSI and NAC+display connected to Arduino given that you can access and change VIN in BSI (if it's not locked)?
Haven't investigated the topic much, but it's worth looking up if it's doable...
