Snoopy-Do

This happened to me my aerial fin had let water in and caused the sender unit to keep showing I was 200 miles away. Rather than pay Audi a £200 fee I had a local car sat nav shop fit the new part behind the glove box. You can buy the replacement part much cheaper on eBay and it works exactly the same, The fin is bolted on the inside and you have to remove the liner etc. So decided on the easier option.
