I will stop short of producing a step-by-step guide on how to replace the head unit because there are a lot of variables and there will still be some work required to connect everything exactly as required, but I hope this information is useful to anyone attempting the same
There are loads of other videos/posts about taking the dashboard apart so I won't repeat that here
The parts I purchased:
Dash fascia adaptor:
I used AVC 381130-11
https://shop.acvgmbh.de/index.php?s...e(detail,flextor)&_edit=3222&search=381130-11
InCarTec 50-897 and other similar models available
FM Aerial harness adaptor:
InCarTec 21-118
https://incartec.co.uk/product/Nissan-06--Aerial-cable-adapter-to-DIN-radio
Adaptor for reverse camera (requires modification as the connector doesn't fit an accord):
https://www.aliexpress.com/item/1005004625021947.html
or (doesn't require modification
https://mobilemaxcaraudio.com/produ...-tsx-factory-backup-camera-retention-harness/
Steering wheel controls adaptor + harness adaptor:
InCarTec 29-679
https://incartec.co.uk/product/Hond...-Jazz-steering-wheel-control-interface-29-679
Climate control retention cable:
https://mobilemaxcaraudio.com/produ...rol-conversion-harness-navigation-to-non-nav/
ELS amplifier retention interface:
https://mobilemaxcaraudio.com/produ...cura-els-audio-amplifier-retention-interface/
Without this the factory amp is stuck at a low volume level
Arm rest USB retention cable:
InCarTec 24-251
https://incartec.co.uk/product/Honda-Mitsubishi-USB-Retention-harness-cable-24-251
or available more cheaply from Aliexpress e.g.
https://www.aliexpress.com/item/1005002503470909.html
Display screen from base model car:
Should be loads on ebay but if you are struggling search for "D099T"
Dash storage cubby from base model car:
Again should be plenty on ebay. If you can find someone breaking a base model car, you could ask them to send you the display screen, dash cubby and the wiring/connector from the display screen to splice it in yourself
Reverse light wiring
You can take a reverse light feed from the wiring in the driver's fusebox (on the right of the accelerator pedal)
The light blue wire in this area connector is the 12v feed for the reverse light, as per the wiring diagram:
Main harness wiring
This connector removed from the "Audio Unit" (CD changer) is where most of the stereo connections are made:
Here is the pinout of this connector:
The ELS module from Acura Audio Garage came with the Honda connector on so I didn't need to do too much to this.
The steering wheel control module connects to pins 5 and 16 of the Audio connector "A" (the connector above) as per this diagram
There is also a wire that connects to the connector removed from the bluetooth module in the passenger footwell (you can get rid of that as its no longer needed) which allows the answer/end call buttons to work
I had to splice these pins in to the harness provided with the ELS box as that one came delivered with wiring for another steering wheel control setup.
The factory amplifier in the boot receives a line-level signal so you need some RCA connectors on the harness (Pins A18,A19,A22,A23, as per above), to send the signal from the pre-out connectors on your head unit
The end result will look something like this (this was a previous attempt that I hacked up!)
