Which brand of car navigation works well?

Car navigator brands include: Castar, Desai Siwei, Jidu, etc. They have their own advantages and disadvantages.

Castrol is an old-fashioned car navigation manufacturer, and it is easy to see them in 4S stores in Auto Parts City. I believe many experienced riders are familiar with it. Although new brands like Jidu are not as well known offline as Castrol, they are very popular among young riders in the new era. The "intelligent big screen navigation", which is characterized by meter, has become "the benchmark of Internet car navigation".
