Good evening, I am just back from my summer holidays and have spent a couple of weeks driving my 2018 A4. I have found that it keeps dropping the Android Auto connection frequently which means listening to Spotify or using Google maps is impossible. I noticed it seems to be in areas where the mobile signal is weak but am not 100%. Can anyone suggest what could be causing it and what I could do? I bought a brand new decent cable so do not think its that but am open to suggestions. I really want to use it as when it works its fantastic.
