True, in terms of fitting and looks its the best. When I bought my 2nd X it had basic unit. After exploring all options I ultimately went for original TW unit. For me even purpose wise its best, I probably mentioned earlier as well that I only need it for reverse cam and Bluetooth which it does absolutely perfectly
Maybe not acceptable for many people but for my taste and requirements the audio quality is also just right. Not a fan of super high volumes or bass tubes so the stock system is perfectly fine for me once you adjust levels
