11/8/2022 0 Comments Nissan map update hack![]() ![]() If you have the firmware update you can check the same, but I'm sure it'll be the same firmware as I have where it does work for me. Do you have access to a copy of the D554 firmware for yours or D605? Before I installed D605 I unzipped it and checked all the relevent files and mount.sh to make sure the hack would still work. I'm not aware there are different firmwares for different real Connect 3s. I have seen references to a Connect 3 with no sd card slot (also referred to as Connect 4 in other places), but you have an SD slot so a proper Connect 3. Mine is hardware version 31 and has a different facia but I wouldn't expect that to matter. I have a Connect 3 in my Pulsar and it worked on that when running D554 and since I've updated to D605 it still works. There is also a custom file header before the PNG header which appears to contain encrypted/compressed data.Īpologies this is so rambly - just thought I'd share what I've observed so far and wondering if anyone has had any success in decoding any map data. In JUG00378.pnn, however, despite indicating the IHDR chunk is 13 bytes, only 10 bytes of data follows until the next chunk name is reached. Looking at the files in a hex editor quickly reveals they're using PNG format, however the chunk data appears to be partially compressed/encrypted.įor example, a typical PNG IHDR chunk contains the chunk length (13 bytes), chunk name ( IHDR), chunk data (width, height, etc.), and CRC. ![]() phn is "high " as these always appear to be larger than the. ![]() a different colour depending on the display mode of the navigation system. My first guess would be that the final "d" and "n" in the file extensions could stand for "day" and "night", i.e. For example, the file name "JUG00378" appears as: There appear to be four versions of each file. The files are contained within a folder called "3D_PICT". Specifically I'm interested in decoding what I assume are icon/graphics files used by the navigation system. Some plain text files exist such as XML, CFG, and TXT files. Most of the files are binary formats - some are known file types such as SQLite but most appear to be proprietary. The SD card contains a folder called "CRYPTNAV" which contains around 15,800 files, roughly 5.7GB in total. Mine came with a "V5" map data SD card, similar to the following: The firmware version is D554 (accessing the service menu is slightly different - I followed this video). Some context: I bought a 2018 Nissan Pulsar (Tekna trim) which comes with the following head unit: I was wondering if anyone has attempted to reverse engineer any of the map data that comes with certain models. Thanks for the writeup it's made for a very interesting read today. ![]()
