Rv37 400r questions

[elir32]

Hey guys. I have a 400R on its way to Australia from Japan currently and have a few questions I’m hoping others may be able to help with.
 

Wondering if anyone here has had any luck getting the Sat nav unit to work in Australia!? Assuming the Stereo is as simple as a band expanded and tv won’t work?  Seeing as they’re based off a Q50 which is Aus delivered is there any way to link that system to the nav? Nav modules and head unit are different part numbers and appear slightly different at the rear with plug ins etc. can I put my xtrail sd card into the rv37 and will that convert the maps or update to Australian? Has anyone got any advice here?

 

 

also has anyone fitted the factory remote start and Security system once it’s landed in Australia? I put an enquirey to Nissan Japan in via a third party, and they suggested it needs a Nissan Japan dealers device to setup and couldn’t guarantee if one here could do it or not. They can supply and I can physically fit it but to setup I would need a dealers device. Any information here would be appreciated also. I’ve seen one here with it fitted already prior to leaving Japan at a dealer/inporter, so clearly passes compliance and works when fitted Japan and doesn’t need changing here. 
 

 

also, does the tyre inflation sensors work here? Does anything change with them when the vehicle arrives? Where are they actually situated? I’ve read they have batteries and they need to changing at times and seems like resetting involves the nav system? 
 

any help here would be appreciated and any other aust specific information to help would be great. Looking forward to see what the current generation skyline is like and eager to see how many of the gadgets can be utilised here.  Thanks in advance

No idea about the remote start part.

If the V37 nav is anything like other Nissan JDM vehicles, you can't get the factory Japanese nav working in australia, a card from a different car almost certainly won't work, those cards are usually matched to the serial number of the DCU.  You could be possibly swap out the components from a AuDM Q50 to get it working, but if this is a new model (2021+) 400R, then you will lose the newer features like ACP/AA.  That said, if you have ACP/AA, just use google maps..

I assume a band expander would be required to get the local radio stations, but don't forget the Japanese FM band is narrower than ours, so you still might not be able to receive all Australian stations.

I can't see any reason the tyre pressure sensors won't work here, there is the sensor unit inside the rim and the receiver nearby in the wheel well.  I have never had to change the batteries on my 2015 Q50, so I assume they last quite a while.  A straight battery change shouldn't need them to be re-registered as they are the same unit, that should only be required if you replace a sensor with a new one.
 

Word of warning, if you ever go into the 'secret' diagnostics mode on the main screen, DO NOT EVER do a 'reset' in this menu, it will erase all of your model specific data in the DCU and you will need a trip to a dealer to re-program it all, which would be particularly painful being an import.  This applies to the AuDM Q50 too.

Thanks mate for that reply. Very helpful. 
 

it’s a 2022 400R so would most likely lose those features as you say.  
 

I did a quick compare of a rv37 nav and heading for sale in Japan to q50 model. I’ll pop pics below. Seems 

Japan spec head into top, nav unit second below it 

 below pic Q50 aud delivered  

 

differences seem to be Aus delivered has a different plug top left hand side of head unit- not sure what and where it goes.

 

and nav unit Japanese tv37 had an extra plug put    Again I’m really not sure what each of these differences mean!

 

 

 

the actual plugs on a v37 and q50 screens look identical on both screens… pics below for comparing. (One screen was is a us delivered one) but should be same gps signals etc as Australia. 

 

If it were as simple as swapping a nav unit from q50 aud delivered im interested -just want to figure out what the missing plug is for before spending big $ on a second hand part for it to not work, and I guess with the head unit, if the band expander does the job (I got a 20mHz so should get the range I’m after) so should narrow my issue down to nav unit only.  I’d love to know what the extra cable on rv37 does and if I eliminate that part what it’ll do to the setup, 

 

and also, if I can figure out what that head unit plug difference is, what does that cable do and where does it got can it be altered or re-plugged?!

Excuse my ignorance what is ACP/AA, what does that stand for? (Apple car play? Android air play)?

so If I swapped head units to save using a band expander, I’d likely lose those better features to have an oem Unit operational. Better to use a band expander and retain AirPlay options and newer version of head unit  

 

provably best to band expand it, and focus on the nav unit.

th isn’t  a big deal/ would be cool to have it working  from what I can tel we use a PAL Signal and Japan uses a NTSC signal  I don’t know if there’s a co better or if the screen only reads NTSC, or if it’s the tv module that needs replacing… no big deal don’t need it but more of a curiosity thing on that!

 

Thanks for the info re tyre sensors, helpful and great to know.  I was reading the online manual off Japan website and it seemed to make it sound more confusing than it is  I guess a rim replacement would require the sensors to be moved to a new rim to carry that option over?!

 

 

Thanks for the info regarding diagnostic mode. I appreciate your help mate. Trying to brainstorm here to find a solution to get as much gadgets as I can working! I plan to get my local Nissan tech to have a look too who used to be at an Infiniti dealer back in the day to see if any thing they have or idea can find a soliton. But hoping anyone here has gone down the same route to make life easier!!

 

i guess identifying the cable/plug differences and what they do would be a great way of finding out if the units are transferable 

 

thanks again

Hard to say what the extra connector is, it looks a bit like a coax type connector, so possibly a separate radio/GPS antenna, or even another camera input?  The V37 series (including the Q50), did go through a model refresh in 2020, since Australia didn't get any Q50s newer than 2019, we didn't get any of the refreshed models, so there could also be other unexpected problems to overcome to swap an older Q50 head unit into a new model V37.

There probably aren't too many people around that have made these sorts of changes to a Q50/V37, so you might end up being the first if you do decide to go ahead.

ACP is Apple Car Play and AA is Android Auto, they are roughly the same thing for the 2 major phone operating systems (Apple's iOS and Android), it allows you to connect your phone and access a number of your phone applications on your car system.  With Nav apps included, so you could use google maps/Waze or whatever your favourite navigation app is, instead of using the built in navi system.  I think this would be a better solution if it is only Navigation that you are looking as swapping the head unit for.

GPS signals are the same around the globe as the GPS satellites continuously circle the globe, but it is the head unit that doesn't allow you to load Australian maps, or at least no-one had made an Australian map that will load up on the JDM head unit.

Regarding the TV standards, I assume you are referring to the AV inputs?  I haven't ever tried to use them, Japan used a slightly modified version of the US NTSC system, and Australia uses PAL for composite video, that said, I wouldn't be surprised if a video input could work with either system.  That is mostly irrelevant here though, unless you plan to use those inputs for something?

I think the solution Pac posted in the other thread is the way to go with the top screen; I have an ADM Q50 and I only use it for 2 things:

1. Reverse or front camera as triggered automatically by Reverse selection or the front sonars, and you can also call up the front left (or front) camera when parking by hitting the camera button on the centre console if necessary

2. Navigation. I can assure you that getting hold of a 10 year old nav system is utterly useless. The ADM system still has Inifiniti dealers marked (always give me a good laugh), is missing all new freeways, uses fixed speed by road type to determine arrival time, no traffic/re-routing, no speed cameras, no user reported cameras etc etc you get the idea

So, Pac posted in the other thread about a box that plugs into the USB C and gives you full Android OS to run whatever modern/connected nav you want on the top screen, and it still automatically switches back to function 1 above when required because it runs within the head unit.

The other modern alternative is the latest version of the Tesla screen like this:

But I haven't looked into whether it is compatible with Australian 4G bands yet so it may require a separate 4g dongle to provide data

+1 for getting a screen off alibaba, CarPlay/Android Auto is vastly better than whatever navigation cars had 10 years ago.

I got an Android screen for my 2015 BMW, huge difference. Fully compatible with factory stuff including iDrive controls.
