twtwtw Yes, I contacted Mekede and they sold me an extension cable. Annoying to pay for it but it was cheap, cant remember how much but not worth the effort to complain further despite telling them the supplied wiring is not long enough on their Alphard specific kit.
I fitted the DUDU7 with optional tyre pressure monitoring, DAB+ and 360 camera system. It's good but there are quirks with the head unit that get to me sometimes. The oem map you cant zoom in and keep the viewing distance, it always reverts to a default zoom view. Another is the built in fan comes on and off too much and its easy to hear it. The screen also sits too low in its housing so the very bottom of the screen starts to be cut off slightly.
Would I buy it again? Maybe. The wife wanted a 360 camera system hence why I ended up here. I think I would try another brand next time but any android I have installed I have never liked. Modern stereos in general are garbage no matter the spec of them. So many features the basics are forgotten.
