Which is better, Gefei, Casta or Philips Navigation, or Toyota Crown?

In my personal understanding, Philips should be the best here. If ranked by quality, it should be Philips > Gefei > Casta.

Castrol has the best cost performance. Unless there are special requirements, Castrol can basically meet you. Ge Fei is more beautiful than the crew on the main interface. The function is roughly the same. The so-called Philips is actually contracted by Huayang. Of course, although it is OEM, the quality is still guaranteed. If the budget is sufficient, I suggest going directly to Philips. I hope I can help you.
