Is it possible to do a firmware update on Navi 600 and if so how? I've got a 2013 GTC and wonder if it's been updated since. Can't find any info anywhere.
Normally the updated map SD cards carry software updates on them.
Firmware would be done via a dealer or someone with an MDI with access to TIS.
But we are only advise to apply updates if directed to via a TSB. If everything is working there is no real need to update it.
