I have this unit , its not bad , but as ive mentioned in other threads there is a few functions that are missing such as the side traffic alerts in parking mode ,obviously your going to lose the hud speed limits because you wont have factory maps . I'm not sure about bi-model settings because I have an after market system with remote activated bi-models but I would imagine it does . Just keep in mind that most of the functions are controlled by the Aerpro facia kit and not the head unit itself . The Kenwood system is another good one but has a smaller screen . Having Android/carplay far out ways anything that you might lose .
EDIT: Autobarn sell these units so you could probably tee up an installer there . The instal isn't easy if you want to put a pocket below like I did. The guys I bought my Kenwood system are in Perth , they seem quite competent , there called Universalfuze
EDIT AGAIN :
@TazzI 's option might be the best when he gets it sorted , which is the first link VS 5.0 gave you .
