The answer unfortunately is no.
However, there is an option to have Apple car play or Android Audio installed without affecting any of your original audio system and can be installed by Ben Hau (no affiliation to The Alphard Club)
Below is a video showing how this can be done.
Another option is to have a new audio system replaced which can be down from around £300 which will mean a new head unit with the latest Apple or Android Software with Maps etc.
Optionally you can add videos from Youtube or Vimeo to your guide
