Revision B and C revision units

These units will become SW revision D after the upgrade however when coding the unit using VCDS you will receive the error
“Coding Rejected, Error 31: Request Out of Range”
Before saving the new coding manually add a 10th byte (00) at the end before pressing “Do It” as per the example below

9 byte coding (B/C SW revisions):

10 byte coding (D SW revision):

Warning! This upgrade will not create the new partitions required for the new POI system if you upgrade from 1xxx/2xxx. Upgrading from 3800-3910 is required so the new partitions are created.

Warning! 7L6 Touareg RNS 510’s are no longer supported since version 3870 due to the Touareg being fitted with the RNS 850. Version 1200 was the last version factory loaded on the 7L6 units with a hardware revision B.

Warning! There is a remote chance of you ‘bricking’ the unit, this is a fraction of a percent but it could happen! The process takes around 60 minutes.’

Warning! There are a small number of users where the RNS 510 does not know where it is after it’s been powered on, details of the previous location are kept in the unit but at this stage there is no pattern to this problem.

Warning! There are a small number of users where the RNS 510 display has a dim backlight after upgrading. See the post “Volkswagen RNS 510 Backlight Dim after upgrading Firmware” for more details.

Warning! Users with cars MY07 and earlier may experience power drain issues after the upgrade. See the post “Upgrading 2nd generation radios (RCD 300, RCD 500) to 3rd generation (RCD 210, RCD 310, RNS 310, RCD 510) power drain issue” for more details.

Warning! Users with the Skoda UHV bluetooth 1Z0 035 729 B (1Z0035729B) may want to delay upgrading the firmware, there is an issue with the RNS 510 no longer displaying the phone book and/or the call details but signal strength etc are visible for some phones. A HTC Diamond for example worked fine before the update but only partially afterwards however an iPhone 3G worked fine before and after. This is not a problem with the 1Z0 035 729 D (1Z0035729D) Skoda UHV bluetooth kit. The MFD functions as per normal with phone book and last calls listed correctly. Android 2.1 phones work fine with the update.

Note! Test/Setup Mode. The firmware can allow access to enter test/setup mode without Vagcom/VCDS access see Accessing the Setup Menu on the RNS 510 head units with firmware later than 1100. The procedure for entering the test/setup mode for those with Vagcom/VCDS is slightly different as well. To enter the test/setup mode when the RNS 510 is operating press and hold the setup button, keep holding it when the radio menu appears and shortly after the test menu appears . I had to reboot my unit after coding it but it may be possible a power cycle is enough.

Note! Failure (Gateway Error 202) You can downgrade back to 1100 by inserting the 1100 firmware and rebooting the RNS 510 (Setup + eject + info).

  • Laci

    Hi, Can someone tell me a step_by_step tutorial, how can I check the actual HW/SW version of the RNS510? Long press of setup not working…. Thank you very much

  • @dri@n

    Hy josi:
    I have a question for you.
    It is possible to make a modified SW4020 that reads the FLAC audio format, using SD cards reader?
    I find it absurdly that the audio can not be read than CDs and not the card.
    I wait your answer.
    Best regards ,

  • Stas

    Do not use this firmware if you have Skoda with Mobridge bluetooth. After upgrade all functionality regarding phone book/call list does not work.
    Tested with Galaxy SII and Blackbary with the same result. I think I’ll go back to 3984 – I do not see any reasons to stay with not working 4024.
    Haven’t found anything where 4024 is better than 3984 but has broken phone functionality.

  • Behavz

    I can confirm that @lYsa version does work with my RNS-510 VERSION C. Installation took about one hour with regular reboots at mid and later stages of installation. You will hear a pop from your speakers when it reboots but this is normal. You map have to install maps separate after this because it erased all hard drive date for me, I am now looking to install v8 maps.

  • efipaul

    May be a dumb question, but is this firmware for US-spec units as well? I have a rev E unit that says it has FW 3696, but I’d like to try this one.

  • Olly

    I have the C version 1T0035680C H06, SW2720, map version 7676
    am i able to direct upgrade to 4020 or do i have to pass by an intermidiate stage. i see above it mentions upgradng to 3xxx, but as far as i can see these are Beta. Do i still have to upgrade to one of them before 4020?
    will i need the map dvd handy in case i lose it? this is a retro fit unit, so no warranty, and dont want brick it 🙂

    many thanks

  • Flo

    Hi @all,

    I think, we need a new thread called “Volkswagen RNS 510 Firmware Upgrade to version 4120”!!! 🙂

    Does anybody know, if a 4120 version is available? Would be very very great!

    Thanks a lot!


  • Korny

    Hi all,

    I have this unit: 3T0 035 680 A (3T0035680A) H42 with SW 2724 in my Skoda Superb.
    My previous attempt to upgrade the unit (to 3xxx) resulted in a unit that was bricked. I could not operate the touch screen, had no radio and the unit wouldn’t turn off even if I closed the car or pressed the on/off button.

    Some guy has reverted the unit back to its previous version (2724), took him an hour or two.

    Still I want to upgrade the unit because of the dutch menu within MaxiDot and the Voice Commands.
    Does anyone know what was going on with the unit and if it is save to upgrade it with the 4xxx firmware?

    Do I need to go to a previous version because I don’t understand the line of text:

    Units that can be upgraded include (still being compiled may not be 100%)
    3T0 035 680 A (3T0035680A) —> to version 2704. <—

    Hope someone can help me out…


  • Shanny

    Hello dears,
    is anybody here who has got a solution for failure: “Error – EcuOrder.txt – Error reading HW Vers”?
    Thanks Shanny

    • Yess

      hallo shanny i have the same problem with my rns 510. Did u solved the problem and how? Because i got crazy and didn’t find out how to solve this?


      • e1

        I had this problem. I found a guy, who had special cable for RNS 510 diagnostics, and he recovered my bricked Columbus, and upgraded the system to his modified FW version 5218.
        It cost me 100 € + 300 km trip + 40 € for speeding ticket… :-/

  • I downloaded from the second link (the first wasn’t working) and installed it with few problems.

    It stalled at 29%, but carried on through the complete installation in about 1 hour as expected. It also wiped my music and map data from the Columbus unit.

  • Praj

    How do you check the version of firmware you have as if i have an old one i will have to use 3xxx first then 4xxx

  • craig

    Hi All

    is there a newer version than 4020 yet for the H version RNS 510 ?

  • iceberg

    Links to files are dead !!! Any alternatives ??

  • blackoth

    I have a 2009 Scirocco but I don’t know which version of the unit (maybe C?). How do I check it? Can I upgrade to this?

    And what is the recommended way to upgrade? I think it currently has 2760 installed. Should I first upgrade to 38xx/39xx? If yes, which one?

    And what is this VCDS? Do I need it?

  • salam

    this last version is not working, i tried it just now manytimes , i get error in ( APPL UPDATE ) step . it is better keep it with the old one 🙁

    • J. Kim

      I have C/LED-version and this firmware is installed/working w/o any problem. I don’t know what’s the functional difference, but I can feel a little speed-up.

  • Is this version only for European units? I have a 2012 tiguan with rev E unit and 3696 fw. Can I upgrade?

  • Daniel

    Uppgraded from •1T0 035 680 B with SW 900 and it worked fine. But HDD formated. So new maps V8 installed too

  • John

    Reg. 4120: Burnt on an old Verbatim DVD+RW, (slowest speed in Alcohol 120, other settings as standard) worked perfectly.
    Extra feature in 4120: If you have acoustic park assistant, it will mute the radio as soon as you set the car in Reverse gear, this is very good, since I’ve aways manually been muting the radio when reversing (our driveway is narrow and cornered)

  • Salam

    is there anybody tried this version? I had try it but it can not be finish, its stopped in APPL UPDATE, show ERROR in disply. anybody know about this version or try it successefully?

  • xMAXx

First time i had swl error, it dont install, a message with reset the navi comes and when i do that it open again with old 3810. So what i do i find another version of fw 4020. I was installing fw, then the navi close i think my accu was little bit off and i open again, the cd come out the navi and it sais SWL ERROR: software loading error (010303), a swl error occured and now the maximum SWL Error Count has been reached. Swl is now Blocked until a power cycle is instigated using the following 3 buttons: + + . I do that but not helping always the same error and sometimes only the VW Logo and thats all nothing more no radio no sound no navigation, it dont open anymore. On my rns510, i dont have the mic button but i have a TONE button. The reset works with this button but always like i said the same error. What can i do? I tried Installing fw4020 again with burning on dvd. It dont help. Is my rns 510 damaged forever. Can i not repair this.

  • Kam

    can this update be used for the australian version?

  • Andreaz

    Nice site! 🙂
    I have a 2011 Superb with 3T0035680C HW H60 SW 3984
    Upgraded map from 7551 to 7918
    But the list of news for the 4xxx version have things that I already have?
    GPS cordinates
    Speed limit
    Screen off
    Clock when off etc.
    Any gain or point to upgrade the sw for my unit?

  • Adel

    Could only download the ISO image, but not the RAR files. Upgrading my RNS510 from 3810 to 4020 and I get an error at about 14% through APPS upload. Tried downgrade to 2660, no luck. Just can not read the CD after that point. Tried burning CD at lowest speed, also DVDs but nothing worked. I noticed the ISO has the bit for the test mode turned to 01, and comment above it to Active, but the remarks above in thie post suggest the comment remains as ‘NOT Active’, removing the ‘NOT’ from this line reduces the file size by 4 bytes. Any ideas how I can get 4020 to work?

  • Redyak

    I have the same question as Korny. The explanation mentiones •3T0 035 680 A (3T0035680A) to version 2704. I have the same unit an C revision but with H41 and SW 2724 on it. Can i upgrade or not.
    Thanks in advance if someone can clearify it for me

  • Antonio Osuna

  • ririm69

    Hello and thank you all for sharing with us your knowledge.
    I will itemize all of my history because I dry a little.
    I bought a bit ago rns 510, 1T0 035 680 hw 0520 down motherboard and I replaced a motherboard firmware B version HW11 3980 which is happening in D.
    It works very well indeed, the concern is that I’ve realized that my Hitachi HDD is faulty, not detected in media and on my pc.
    So I installed another hdd ide 2.5 inch a place and that, it is detected, I can even copy mp3.
    My problem is that I wanted to format my new hard drive to install v9 card.
    I do not own the image of the old hard drive and it is impossible for me to gain recognition on my pc because it tells me not initialize status.
    When I load any version of that 1100 or 2660 I authorize the downgrade on the RNS 510, the update starts, but I do not see the gateway appear in the progress bar or the hosts or APPS or HDD,
    RADIO, MPEG only SWL bar starts, and the final installation of the unit tells me error ecu. Txt error hw version of I precise that when I run the recovery cd, my car radio back in operation, but still with the non-partitioned HDD.
    Another problem noted yesterday, my car radio is not recognized in my vehicle, I said, no sound, not to tune, however the navigation function works very well on the DVD only.
    And VCDS along coding gets error 31 request out of range, even in the two bytes missing.
    There was there a firmware that solves this problem?
    My new HDD is to blame?
    Thank you for caring about my problem.
    Thank you very much.

  • Works great, put the firmware on a normal CD. Thank you.

  • Simon

    Where can I get the 2760_ogw file now megaupload is down please?

    This firmware works great on my RNS B unit in a Skoda Superb MY09, however at certain dusk/dawn light levels the screen is very dim due to the auto illumination. 2760 firmware work perfectly but I loose the nice smooth navigation etc. The 1200 old CAN gateway fix from josi also sorts the screen dim on 4020 but I loose the volume up/down on my MFSW.

    So I can just get the gateway update from 2760 I think everything will work perfectly.

  • Milan

    I have this navigation. Yesterday i was on a 24h trip 1970km. Next day i can’t swich on my unit. It shows the VW logo, and restarts. I checked with VCDS, i can see on the CAN (until it restarts again). HDD is ok.
    Maybe i try the FW updade. What is the password?

  • Peter

    Did you end up getting this fix and how did you go about it? I have the same problem as well 🙁

  • Milan

    no… I tried everything. This is a maybe a mainboard fault. I found one people who offer repair for this problem on ebay

    I will buy an used RNS510

  • aMPI

    what is a password to rar???

  • Phil Knotty

    Hi, is there a fix in here anywhere for a the iphone 5 non compatibility issue when you try to pair up?

    • redyak

      THat is not in the RNS. You will have to change your stadard nokia Bluetooth under the passenger seat with a unit that supports smartphone. They re to find on ebay and the swap is easy

  • James Fortey

    I have recently upgraded my UK Skoda Superb MK2 MY08 Columbus 3TO035680 HW11 SW1164 14/11/2010 (not sure of the version) to the official 3814 firmware accessed through links on this site without making any modifications and experienced no issues so a big thank you!

    I would now like to upgrade to the official 4024 firmware but cannot locate any active links, do you still have a copy? If so I assume that as per my previous upgrade there would not be any modifications required.

    I am also assuming I cannot upgrade to the 4124 firmware even if I could find an active link to the original SWL.


  • Andrejs

    It will works with RNS 510 part number 1T0035680F SW-Version 3970?
