When I ordered the A3 I didn't add the Sat Nav option which was a bit of an oversight. I contacted Newbury Audi to see if it could be added afterwards which they confirmed it could. It's all ready to use you just need the SD Card with the data I believe. They want £495 for it. When I asked for a deal they advised that this is the factory price and can't be changed. Anyone know if this is correct or had a better deal anywhere else?
