BNS 5 Nav Unit Error

[Rossco]

Hi Guys,

Just a quick one.

I've purchased my first Audi so its all abit new to me.
It has the BNS 5.0 Nav unit installed, however I don't have the map disc. I am getting a error on the centre display of the dash saying 'No Nav Disc' or similar.
The only way I have found to clear this is to turn the headunit off, the display then reverts to the usual, trip etc info.

Is there a way to clear this error without having to turn the unit off? (other than purchase a disc) I've tried every button I can find - accidentally reset the trip twice now! 😧
