If you have read my earlier blogs about the RNS 510 then you may know I have been working on creating custom startup logo’s for some time.

For some time now I know how the images are encoded and decoded between Windows bitmap and the native RNS 510 image format.

Recently I identified the checksums in the image data, and the differing parameters for the Seat, Skoda and VW versions of the RNS 510 firmware.

Work is in progress.

I didn’t notice it before but the new RNS 510 firmware (3810/3814/3816/3818) has a new startup logo for the Volkswagen firmwares:

I wrote earlier about the startup logo’s on the Volkswagen RNS 510 navigation.

Today I can finally tell you that I succeeded!
I changed the startup logo to the logo from the MFD2 DVD as you can seen on this picture:

About a year ago I wrote a checksum calculator for the Volkswagen RNS 510 navigation unit.

The checksum is a variant on Crc16 and is present either at the end of certain files (eg #CRC16:db1d) or as a special file with the name CRC.16.

The tool is a little exe that takes the filename as the only parameter.

Have fun with it!
