Our 2014 A3 Cabriolet 8V does not have the Navigation feature built into the MMI Sound System. It does have the pop up MMI display but it's only for Radio & Phone connection. The Audi Multimedia System is located in the glove box and I have found that ones from the same model vehicle but with Navigation are available from written off vehicles at a reasonable price, would swapping one of these into our A3 give us Navigation or does anything else need to be changed. I tried asking Audi but they are very tight lipped and have quoted almost A$3000 to retrofit.
