I am a cord freak. I had cords and always hide them, this was a challenge but not bad. Sound quality through fm transmitter is really good so I could eliminate the aux cord. I took apart my dash/ radio area to run the cord behind it and hide it. It look about 40 minutes but I am not a car girl so took longer to figure out how to take it apart lol. But the end product is beautiful and I am very satisfied!!My car is a Lexus CT200h so I can’t just replace the screen for car play, I would have replace the screen and completely rewire everything which I was not doing and would have cost $500 to do it myself and probably $1000 if I bought the needed materials and paid someone to do it. So to do this for $230 is great. Such a great alternative if you have an older car but don’t want a new car just for apple car play!!! Recommend!!!!
