Download the files and extract them using winrar and you will have a NRG format ISO file to burn. Using Nero burn a DVD+RW or DVD-R (CDR works as well) at a slow speed (4 x is ok for DVD and 16 x for CD). Make sure you use quality media and keep the burn speed down as low as you can to ensure there are no problems during the installation process. Also note that you may need to edit a file before you burn it (see below) if you want to access the setup menu without Vagcom/VCDS.

Warning! This upgrade WILL delete your music and/or maps if you have a firmware version PRIOR to version 1100/1102. Units with a firmware version of 1100/1102 will not have music and maps deleted.

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! 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).

Steps to load firmware

1. Unlock and/or open the car
2. Do not start the car
3. Turn the RNS 510 on and insert the firmware CD/DVD into the drive

Download Unofficial SWL recovery CD

This is used if the unit is stuck with Gateway Error 202 or similar and is unable to boot after the upgrade. It’s based on the 272x firmware but can be used to recover RNS 510′s running any version. Insert the media into the RNS 510 and start a new SWL process by pressing Setup + Eject +Info/Mic (top right hand button next to the DVD slot). It will attempt to restore a new SWL process and will enable it to boot up. (Thanks again to Josi)
