Very seldom do you get "original" when from chinese, most are clone hardware with "stolen" proggy on it. They will try to make it "fit" and "work", but not always successful (cost of cheap pricing.) From looking at the codes so far, it looks like it's a Primo version with lots of codes copied from other products. There are lots of "profiles" for devices (even android ones) If you buy say Pioneer directly* from them, the proggy (Avic) are made/tested for that unit (people posted it and everyone assumed it's for any devices) so there are functions that won't work when not used on the Pioneer unit (lots of "useless" codes)

* They have license and support from NNG to use their proggy
