hi
how can i know if my car is ISO Based or Quadlock,
because i buy px99-x89 adaptor and he dont work, maybe my car is quadlock and i need something different?!
thank you
You should have received several manuals/books/logs with you vehicle and within these should be one on the headunit (HU) and hopefully it may detail within there what connections it has. Or remove the HU and describe here what you see.
