@Dave_R You are a savior . I just installed an android head unit with the same canbus box and had only 2 issues. Audio not working and the back camera (that came with the head unit) not kicking in when putting the car in reverse. Thanks to you, audio issue sorted quite quickly as I was getting worried about potential wiring hell I may have to go into. Mine is also the simple one (not the 18 speaker system) and do not have the back screen either. I bought the android head unit with the 360 camera system, cameras are all working great. Just need to get them fitted properly as my Vellfire did not come with any cameras except the reverse one. This means opening up all door panels, removing wing mirrors, drilling holes in them for the aftermarket side cameras as well as fitting one in the front grill too This camera fitting seems more than I can handle I think so might book with someone although no one these days likes to do a partial job as it makes less money for them Lets see. But apart from that really happy with the head unit, really simple plug n play with the canbus box. Can't go too wrong with the wiring with that (except for the silly audio mistake obviously, I had put Aux in to Aux in not thinking it should be going out from the head unit). All steering controls worked out of the box as soon as you setup canbus and tell the car model (I had to select Alphard). Everything else like GPS, 4G Sim and android auto works great. Might disable android auto alltogether to be honest as its a full fledge android system on its own so I can just install the apps I want and just use the BT for calls with phone unless someone convinces me otherwise . All in all, very happy with the purchase. I have an 8GB/256GB system with the ADAS front recorder and the 360 camera system. Cost me £167 for the head unit (with AliExpress amazing sales). The only problem or slight issue I had was that the seller made me purchase a separate canbus box (£70 again in sales) and that came earlier than the head unit and when the head unit arrived, it also had the canbus box in it 😶 So now I have an extra canbus box which I will keep if the one with the unit breaks down ever.
