When purchasing the vehicle, all advertisements show a navigation system and the dealership never advised me this was an optional add-on. I would never have purchased the vehicle if I had known this. Dealership seems unable to tell me whether Mazda makes an SD card for South Asia for the navigation system. 3 trips to the dealer, 5 sales associates, one manager and all I can get is "use android carplay with a phone made in Thailand" or "we can order a card for about 15000 baht". Besides the fact that this price is ridiculous, now the dealer says Mazda doesn't make the sd card for South Asia. Is there an SD card or not? If yes, who sells it?
