Which is better, the navigation sound quality of Feige g7rav4 or the original car?

1, Gefei navigation is the best navigation on the market, and it is also the only navigation that can obviously improve the sound quality of the original car, with excellent workmanship and materials.

2. Gefei's working temperature is -30 to 80, and it can run normally without crashing even on a particularly cold map. Only Gefei can do it.

3. Gefei adopts Khalid map with the highest market share, which can accurately reach the roads in each village. Other maps are difficult to make, and ordinary navigation does not have these.
