MFD does not display info from the RNS 510

[BlackOctaviaRS]

Hi guys, I've had a similar problem with the Columbus system in the Skoda (same as the RNS510) communicating with the MFD - it was displaying the navigation info and audio info fine, then for no reason whatsoever, started displaying "Skoda Navigation" and not showing the nav or audio info. The car's been looked at twice by the service department, and the verdict is a new Columbus unit needs to be installed, about a 3 week wait from Europe.

Thank god for warranty....

One other thing i have remembered, when i was doing the MDI installation and removed the +voltage and the canbus connectors from the quadlock, they accidentally touched and there was a spark. Does any one know if this is fused on the can bus line? My MFD is still working fine (except any info from the RNS 510... Radio station, nav turns etc). The RNS also works fine.

Unless you want a 1400kg ornament always disconnect the battery before touching the wiring loom. Same with removing connections from the quadlock, do one at a time to avoid putting them back in the wrong spot and take a photo first just in case you're not sure.

The last thing you want is a RNS 510 paperweight which has occurred before to a forum member for mixing power with the CAN bus.
