UPDATE
Now also working with 39xx series firmware. See this thread.
Have an RNS510 and annoyed by how much space is wasted to the map partition?
(The default settings assign 67% of available space for music and 33% for the mapping data regardless of drive size.)
Have you upgraded the OEM hard drive with a larger SSD using JOhnC's excellent guide http://www.vwwatercooled.org.au/foru...diy-60984.html and even MORE annoyed by how much space is being wasted for the map partition?
Then look no further.
Thanks to vwnavi user josi I present a guide for changing the partition scheme using 276x firmware.
Before you proceed, please read this first section VERY carefully:
You will lose all your music and your map data! You have been warned!
Required for the operation:
1. 276x firmware CD. Carefully read the warnings to make sure that your setup is compatible with this version:
Volkswagen RNS 510 Firmware Upgrade to version 2760 / 2762 / 2764 / 2766 / 2768 | my-gti.com
Note for Skoda Columbus owners the test menu is not enabled in this firmware image by default, you need to edit a file before burning the disk according to these instructions:
Accessing the Setup Menu on RNS 510 head units with firmware version 2660 / 2662 / 2664 / 2666 / 2668 | my-gti.com
2. Map DVD
3. Custom files which specify the new partition ratios to make yourself a new copy of the 276x firmware disk with new partition ratios.

4. SWL recovery CD (make a copy if this and have it handy in case it is required) from
Unofficial 272x software and SWL recovery CD
Instructions
A. Create the custom firmware CD. Extract the files from the 276x ISO to your PC. You need to replace 2 files. Use the ones downloaded above in step 3.
You need to replace the existing files with those you downloaded ie delete the originals and rename the ones you downloaded to the correct filename.
The first one is ecuorder.txt.
This file MUST be EXACTLY 414 bytes.
Second file is HDD\HDD_20GB\RNSMIDEC\CONFIG\DlScript.txt
There are two options here. The first is for those with 30GB or 40GB HDDs, and gives you 90% of available space for music. Use DlScript_90.txt
This file MUST be EXACTLY 1821 bytes
Optionally for those with 40GB or larger HDDs, gives 95% to music, use DlScript_95.txt
This file MUST be EXACTLY 1820 bytes
Burn the new CD as an ISO9660.
B. If you are running another firmware version than 276x you will first need to load the standard 276x version. If you are above this version you first need to enable firmware downgrade. Refer to the guide on how to enable test menu in step 1 above.
C. Once you are running 276x firmware, enable software downgrade from the test menu (hold down setup button for about 10 seconds until the 'secret' test menu appears. Go down to system, then enable firmware downgrade. Do not put the keys into the ignition, just insert the CD.
D. Insert your new 'custom partitions' CD. Follow the prompts and let the firmware load. System will reboot a few times.
Once it ejects the CD and restarts into normal mode, you will need to reload your map data. Insert the navigation DVD.
The maps will start loading automatically, takes about 15 mins. If you hit the eject button before they are copied, you will get a warning.
E. Copy some music to the HDD and enjoy the newfound space!
Note: you cannot edit the files to change the ratios as it will change the checksum of the file and the firmware CD will be rejected as not a valid SWL source.
Please let me know if there is anything that is not clear here, this is a first draft. Suggestions for improvements welcome!
