You can purchase a Grom Vlite or Grom Vline 2 from a Australian distrubutor Cushie Audio in QLD for just under or just over $1000 which is plug and play and uses existing system but gives you Apple car play and Android auto at minimum or the more expensive system allows you to install apps etc. I have chosen to do this as you don't have to change original system and you get Waze or google maps, spotify etc.

Owners name is Skot, and according to the all 5 star reviews he goes way beyond customer care most expect.
Hope that helps
