Nissan Leaf SD Cards used in Clarion navigation units are protected with password and it has been reviewed earlier in this post NISSAN LEAF SD card protection. How to obtain SD card password?
Here we will share the SD Toolbox upgrade details for password reading from Clarion navigation unit using debug interface. After some simple modifications in hardware, any SD Toolbox with the latest firmware can be used for this task.
Just a few components must be added on both sides of the PCB:
If this interface will be used more frequently, it’s recommended to use the connector on the SD toolbox and build the cable with a navigation connector. Otherwise, some single test wires can be used to connect the navigation unit.
If a detailed connector pinout is required, it can be found in this post: NISSAN CAN filter installation
Do have any more information on the Clarion Navigation Unit Debug Interface?
Yes, i have some more information. What exactly you are interested in?.
Do you have information on the subsystems that can be accessed via the Debug Interface?
There are several test modes, software start from reserve copy, internal memory access and other. Write me what you are trying to find out or what are your goals and i will help on it if i can.
Please answer how to unlock clarion NXR10 sd card lock?
Password for it can be read in similar ways as for Leaf navigation. I don’t know about debug interface on the NXR10 unit, as I never had it myself.
The fastest and cheapest way to read password is to use logic analyzer and sniff it on the SD card interface.
Can you provide a part # for the connectors used? Thanks.
The navigation unit connector is from TE Connectivity, Mfr. No: 1674312-1
