The altis 1.6 we have at home came with a rebadged Alpine unit. It is made by a pakistani company called Automate. Automate have been producing oem speakers of substandard quality for many local manufactured cars you see today on roads.
As for this headunit, its just a cheap chinese headunit rebranded as alpine by automate in korangi, its plain deception. Ours came with 1 gb ram and some poor processor, it could barely play any youtube videos, we mailed toyota and got it replaced for a same headunit with 2 gb ram. Now its bearable. And btw its not even 720p. It is definitely a very poor unit and toyota is looting people.
