Maintenance/Repairs

Hi there,

already a big thanks for reading, bought an Android Head Unit online: Intel Spreadtrum sc9853i, 64GB / 4GB Ram.

Supposed to be specifically for my car, but so far except for turning on nothing works: no sound, no steering wheel control, no AC temp setting on screen visible…

And it doesn’t even fit, it’s too long to the back, the Chinese seller wants me to go to a local shop where they will cut out a part in the back so it would fit…:

the white round discoloration is where the GPS antenna cable is hitting the plastic panel, guess they’ll cut that piece out… suppose no harm in that?

He claims there’s no other way, the slimmer head units are cheaper models, this model needs this size for better heat dissipation. I feel he’ll say anything to make me not return the unit…

Normally there should be a wiring diagram sticker on the unit, this one came with nothing, no instructions, only a few cables are labeled… only 1 cable is still a mystery:

it seems the harness has a male and female connector, so the female is to connect to the car Power+Speaker cable, and the male goes back into the original CD/Radio? so the CD player can still function, it’s audio should go through the Aux cable?
Seems seller may not know his own device, as I deducted the back inputs from this unit with the same specs:

Looks like mine, according to the seller where the CAN input is market mine supposedly has no function.

The antenna cable has no connector on the harness, so I suppose I can keep using the stock radio? there’s a cut blue wire on the harness labeled Auto ANT, so I could connect this one to the car cable, though would need to figure out how, looks like it has 2 wires (below is for the newer version model L33, but Radio ANT connection looks identical):

the seller claims it’s not needed to function…

my original car: Nissan Teana 250XV from 2010 (model J32, matches the Maxima A35 dashboard/equipment)

So the top LCD display shows the CD number / Radio station / dual Aircon temperature setting.

The backside Radio/CD player:

(deducted the connections from a Google image from Nissan Frontier)

the dark gray is the Antenna radio, the small white should be the Steering controls, the bottom big connector should be for the AC (should not touch), and the remaining plug is the power/speakers wire.

The 2 connections that went into the top LCD display:

the black connector fits into the black one of the Android harness, so I’m assuming this one should carry the AC temperature setting, I’ve seen it’s possible from another sellers picture:

Freaking out as have spent 380 USD on it and it took 2 months to deliver (due to Chinese new year / COVID-19)…

Any help much appreciated, thanks a lot in advance!
