Hello, I activated Smart Link on my swing 3 radio, at Skoda Octavia mk3 MY 2018, so I want to share with everyone how it can be done. DISCLAIMER: You do it at your rensponsability, is not easy to do, and you can mess things out, possible brick you device. Do it only if you have expereince in this kind of activity. Physical tools needed: Tool for removing radio 4 pieces, just google "VAG radio removal tool", cost about 1€. CH341A Mini Programmer, cost about 10€. PC/Laptop Philips screwdriver Software needed (all software in attachment): CH341A driver NeoProgrammer Python (In windows 11, open start menu, type cmd, press enter, type Python, press enter. Microsoft store will open with Python 3.13, click on "Get" and wait to install complete.) Python script for activating CarLink (MEN2SwingPatch.py) Install CH341A driver and NeoProgrammer, make sure python is installed, put MEN2SwingPatch.py script at some accessible location (for example at root D:\). Firstly, you need to remove radio from car, its pretty simple, just insert four "keys" and pull the radio out. Then remove 6 screws from the top and 2 from the bottom, split display from the unit, and pull the top cover to expose top of the PCB. I removed PCB fully from the case to check is there present video chip for reversing camera (unfortunately not), but you don't have to do that. After top cover is removed, and PCB is accessible, you have to find ST 95256 R EEPROM. Put clamp from the CH341A on the EEPROM chip, make sure red cable (clamp) is on the pin 1 (EEPROM). Clamp connector insert in appropriate adapter, and adapter insert in CH341A in part intended for 25XX, make sure red cable facing toward lever. Plug CH341A in computer USB port. All this can be sawn in picture named EEPROM 2. Run NeoProgrammer.exe, go to Hardware tab, select "CH341 Black". Next go to IC>Search>type 95256>select M95256R> click on Read IC. This is the tricky part, if you get all blank result it means that clamp on the eeprom not have a good grip, try to move clamp left-right, take it off and put on again. After 5-6 times of re adjusting clamp I finally got the eeprom content. Save it on pc (for example at root D:\ as 1.bin). Read IC couple more times to be sure that you have good conection to the eeprom chip (if you want to take extra check, you can compare couple .bin with Notepad++ to be sure that you have identical read every time, this is good sign that all is correct). Make sure you dont move accidentaly clamp or PCB. Click on start, type cmd, press enter, navigate to D:\ (place where you saved EEPROM dump and script), type python men2swingpatch.py 1.bin, press enter. If everything is correct you should get printed on display TRAIN:xxx, FAZIT: xxx (see picture "script"), and now you have file named 1.bin_patched.bin. This new file we now need to write back to the eeprom. Get back to the NeoProgrammer, click on File>Open and find 1.bin_patched.bin at D:\, click on Write IC. After writing you can read it again and compare to patched bin, just to be sure its written correct. Now you can disconnect clamp, assemble unit and put it back in the car. Enjoy in your unlocked Smart Link. DOWNLOAD needed software
