So i had a conversation with the dealer in my country, they've explained that J TACS are responsible of installing entertainment systems in all Toyota cars (i.e navigation), however the camera has been installed locally in our country (Rock Optics), and they confirm that these cameras do not save any snapshots within the media thats presented with the navigation system as its a independent UNIT.
Grrr..
… and you believe them? I am sure you need a Toyota LandCruiser to examine. I believe "Magnetic Gray Metalic" color option is necessary for the best video quality.
mrgreen
@Copyright I've investigated a navigation system coming from a BMW vehicle.
The manufacturer of the system told me the harddisk within the navigation system wasn't used to store userdata.
However it contained Bluetooth connection and synchronization information (addressbook etc) of the connected phones.
This is a great topic! I have previously attempted to explore (on a very limited bases) the data stored within later model vehicles, and ran into the same problems you are running into. At the service (dealer) level, technicians have no clue where a hard drive or source of memory is stored on the vehicle, and at the corporate (manufacturer) level, they refuse to provide such “proprietary” information.
It seems logical to me that the vehicle is storing data somewhere. With my smartphone I can check diagnostics on my vehicle such as how much gas is in the tank, oil pressure, and even the level of PSI in each tire. This information has to be stored somewhere. Not to mention the information stored in the GPS unit such as recent routes and destinations. It has been my goal for some time now to crack the car code, and find this data, but I get sidetracked easily!
About 10 years ago my wife had an Audi that was on a long life service schedule. I had it serviced at an Audi dealer and it showed 10,000 miles to next service. (She only drove about 4,000 miles a year so 10,000 seemed about right).
Within 4 months the car had done less than 2,000 miles and the indicator was showing service due.
I booked an appointment and then went back to the Audi dealer to try and find out what was happening.
A guy came out to the car connected a laptop to the diagnostics port and started examining the data. I could see that it contained details of every time the car was started and stopped, how long the engine had been running and lots of other information.
He said that there was a fault and reset the service indicator.
What struck me was the amount of information stored on the computer of a (now) 12 year old Audi.
I believe that there must be a lot more information available on modern cars that is only being accessed and used by motor service personnel.
The problem seems to be that motor manufacturers and dealers either do not know or will not say what is in their cars.
I remember working on a kidnap case, about 6 years ago, in which a Range Rover was used. I located the on board sat nav and discovered that it was manufactured in Canada. Neither Range Rover or the sat nav manufacturer would help. In the end I resorted to the old method of taking screen shots of the head unit.
I wish you all the best with your investigation and would be interested in hearing how you progress.
It might not help with your Land Rover / Toyota issue, but while digging around reading this (very interesting) thread, I found that Berla has developped a vehicule system forensic solution named iVe (http//
According to the documentation, it is focused on Ford/Mercury/Lincoln cars. I have no idea if it works well, but their Blackthorn product is quite good.
Right guys,
So i'de rather try to invetigate the cruiser, anyone has any idea of what sort of storage im expecting a hard drve a nand chip and where is it located? (behind the navigation)?
Maybe we need to disambiguate, separating the specific case at hand from the rest.
There are usually 2 (two) "systems" on a modern car
1) the actual engine/car electronics
2) the navigation device
in some cases there may be (like in CopyRight's case) a third device
3) on-board camera
These two or three systems may be integrated between them or be each with it's own storage (and access to it, if any).
I mean, if we start with the "I had a BMW that…./ I remember an Audi that …." we can get everywhere…..
Copyright reported that the specific Toyota LandCruiser at hand (and NOT any other brand/make, nor model) has a camera that is NOT integrated with the car electronics, nor with the navigation system, as it is (seemingly) an accessory post-mounted.
Though, since images are viewed through the same navigation screen, they must be connected.
It is well possible that the camera provides a simple video feed that is sent to the navigation system display "directly and unbuffered" and as such it is not recorded anywhere, as well it is possible that a kind of storage exists (either in the "camera" or in the "interface box" or in the "navigation system").
There are several "aftermarket" products that are basically a "converter box" for "factory" navigation systems, examples

and each of them may have different features.
The reference to "Rock Optics" seems however like non-valid.
A quick search for "Rock optics" camera leads only back to here, and I find it improbable that there is no mentions of this make/brand anywhere else. 😯

In my personal experience most original manufacturer systems listed above are tied together by a network of some sort, specially in higher end vehicles.
Most US vehicles use CAN, but there many more like Byteflight, FlexRay, LIN, MOST, and even I
C, etc.. There are a bunch of ISO standards, and even open source solution for such networks, including OS (like OSEK).
The OBD interface is like trying to enjoy a digital forensics amusement park through a pin hole.
Okay guys, so i paid them a visit today and had a look at the navigation unit,
so basically there are 2 different navigation units available for Land Cruiser, one was to be used before 2013 models and one after 2013 models.
To have a look at the navigation unit used before 2013

I noticed there was not NAND chip or Hard drive or any storage mechanism, the person has confirmed that the navigation works from the SD card pointed in the picture and thats it.
These are the connections that are available for all models of navigations.

As you can see here it includes two NAND chips with the software and one with the user media i guess, so yeah a chip off is required to read whatever is there. Unforunately in my case i need to investigate a land cruiser 2010 which is different.
Baseline, they confirmed that the units that are assembled locally do no store any sort of data within the navigation system, however most american cards do.
I hope this comes in handy for some of you =)..
