2760/1200 for A/B/C - the same as original 2760 but with gateway code (VUCI) from 1200. 
Recommended for all A/B/C revision units to solve battery power drain with old* CAN gateways.

There is so much to find about this powerdrain issue, that I won't sum up all headlines.
Some notes:
- old CAN gateways are with index less than 1K0 907 530 K for Golf/Skoda Octavia and 3C0 907 530 E for Passat.
- RNS-510 is very picky on CD media, so I suggest to always burn firmware to the DVD media, not CD.
- if RNS-510 complains about downgrade error, insert this media again and reboot unit by pressing 
  Setup + Eject + Info/Mic/whatever top right button together. On US units, use Guide button instead of Setup button.
- no clock on display in standby
- low version RVC from Golf (without separate control module) not working
- doesn't resume VBR MP3
-Video in motion and BMW maps are working too.

If you have the problem, I assume you know what to do further.
For any questions please read the posts there before asking new questions. Most questions have been asked.
I post and, if there's more demand on this powerdrain issue, i'll do more.
