I bought one of these all-in-one head units from Aliexpress, see photo below.
1. It didn't power up (resolved after a circuit board disassembly/reassembly presuming internal ribbon cables loose)
2. The lower mounting tabs where incorrect spacing (resolved after I drew and 3D printed replacements).
So the problem is that while all the controls for the HVAC work, the outside temperature isn't routed through to the dashboard lcd. In this photo the HVAC connector wasn't connected so the dash is showing the last known temperature from the factory head unit. When this new head unit is connected the outside temperature is given as 28c... for Scotland I don't think so. The push on the trip button only allows +-3 degrees either way of the current value.
I've studied the wiring diagram in the US PDF version of the service manual and can see the input signal from the sensor (pin 12, pink wire) - but can't work out where this signal comes back out to then go off to the dashboard to show the correct outside temperature. The chinese seller is useless in helping with this - they insist everything works with the 2003 Accord.
I asked about on the XDA forums but as the HVAC module has nothing to do with the MTCD (Rockchip PX3) unit I've had no luck there.
Anyone been down this road before me? Any help would be gratefully received.
The weird band on the screen is just the shipping screen protector. Screen was perfect underneath.
