These units will become SW revision D after the upgrade however when coding the unit using VCDS you will receive the error

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 (A/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. My HTC Diamond for example worked fine before the update but only partially afterwards however my 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).

  2. Hello,
    I bought a pre-owned VW CC Lux 2009 which came with the very first initial/original firmware. Since there are so many firmware versions do I have to update the system starting with each consecutive firmware? Or could I download this one and install over?
    Thanks 🙂

  3. thank you so much for that CD , i get it today and update my RNS 510 in passat 2009 , I get swedish, arabic and turkish language work very well . take about 30 minutes to update !

  4. Hello, I have recenlty bought an RNS 510 version F with SW3970 installed and in OPS function it saws a Passat back I want to change with an Eos back how can this be done? I have vag com cable.

  5. Guys, Im new to this upgrading thing. Basically what im after is the latest firmware / software and maps with everything possible activated. Any clever people there that can advise which firmware I should use? Do you load maps separately? Also, Im thinking of changing the hard disk in my unit to a 128gb SSD PATA drive so I would like to repartition the disk to a suitable size. Any ideas on what would be appropriate and how to do it. If so, please email me at [email protected] with step by step suggestions. Thanks…

  6. Hello,
    I have an original VW B unit upgraded to FW 2660, should I install directly 3970 or should I use a 3810 or 3810a before?
    Any feedback on compatibility with a V8 7692 map?

  7. You can install V3970 directly but is v3810 have better compability for older units. My opinion is to install 3810 and everything will be ok as the maps V8.

  8. is it possible to upgrade my stock FW to this one (I have a Rev B or C unit) right away or it is necessary to upgrade to 3810 first?

  9. I’m looking for the VIM CD/iso for 1T0035680D HW60 SW 3970. Also is it possible to change the Active Map supplier from Teleatlas to others? Active map : Singapore + Malaysia Map version HDD 7694

  10. Hi guys i have a vw scirocco 2011 model with the Dynaudio package, can i update direct or do i need to make some changes in order to keep the sound. Ive heard that some firmwares one would need to use a vag com cable in order to get the sound back,

  11. Hello,
    I have read earlier, that if you use the MK6 RearviewCam in the MK5s and go to the new Firmware its not working anymore. Is this solved with the new Firmware? Or which Firmware should i avoid?


  12. Dear all,
    can somebody help me. I want to update my RNS 510 but not sure which is the latest version I can use.
    I´ve ask the friendly dealer if he can print me the version information and the following has been printed:
    1T0035680C 1T0035680B
    RNS-MID H04 2680
    Coding long (Codierung lang)
    Working no. 00000 (Betriebsnummer 00000)

    part no. master ($F187): 1T0035680C
    software-index master ($F189): 2680

    I´ve put this 2680 version on the unit a while ago but since that, the steer wheel buttons functionalities are not anymore working. The only thing which is still shown up in the MDF is the normal things like, petrol usage average, distance before zero fuel, etc, but cannot switch anymore to music function, navigation function etc.

    Can somebody answer following questions???
    – Which firmware version is the latest I can use?
    – Is there any firmware version I need to use upfront before going to the latest version?
    – I have Rearview cam, will that work later as well?
    – How can I combine the RNS 510 again with the MDF???

    thank you allin advance

  13. VW dealer tried to update my RNS510 (Passat B7 -2011) but POI’s (built in and my own) are no longer accessible even though they are installed. I suspect that the dealer knows even less than I do about the system. The firmware version is 3970. I’d be very grateful for comments.

    1. I think that the dealer update the unit with a factory original firmware, so it deleted all the data installed in the hard drive. Check if the free space of the disc is the same as before. If it don’t it means that formated everything such as music, maps and pois.

  14. Hello, My car Passat cc 2009 will the Firmware Upgrade to version 3970 / 3974 / 3976 / 3978 fit my car? I have never upgraded it.

  15. Hi
    I am having trouble with the volume (No volume at all) . There is no sound in my VW Golf VI 2012mod, stereo RNS 510 module seems to be working slow. Problem changing language and its very silent…… Any good suggestion? I guess its more than a update we are talking about?

  16. I am struggling to upgrade my firmware and the worse part is that my cd is not working,PLEASE help
