Joying 10.25" Headunit:

Finished the Antenna wire and Reverse wire for Reverse Camera I already had this morning. Not sure I'll use the 4G , usb, mic or the rest but connected it all and routed it to good areas. One of these did everything except the antenna cont. & reverse wire.

They don't put the Antenna cont. wire through the HEAD UNITs ISO plugs, its left seperate off the back of the HU.
Hardest part of the job - chop the blue on the Aepro ISO to Toyota Harness adapter then solder it to the Ant Cont.
That unit turned on literally like that first time. It must have held memory since before it was posted (China) hasn't done a full boot as yet.
Doing research I've found that the SC9853I Intel chip is best compromise for both boot speed and speed in general.
The PX6 is the fastest but does not do the quick boot , I think it is an Intel thing. (or it is just not supported for now)
The Intel chip sits between PX5 and PX6 on speed but still quite quicker than the PX5.
Yeah so that Joying unit is an Intel SC9853I chip does quick boot in about 2 seconds and having used it quite a bit now, its so much faster than these Pioneer, Kenwood store bought brands. You can do heaps on them with apps and stuff. Bluetooth is fast. WiFi great connection speed and range. Reverse camera quicker than the old Pioneer touch screen from 2009 as well. The SC9853I chip also has custom firmware and rootkits as well, and is commonly customised. Pretty happy with the purchase.
