RNS 510 Startup Logo–My thoughts

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.

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

    RNS 510 Checksum Calculator

    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!
