Looking to add support for Ford Fiesta 2015

Good Day

I am looking to add support for a Ford Fiesta 2015 (that doesnt seem to have any available CANBus decoders)

I have the folowing questions:
Is there any documentation of the Android head unit to CANDecoder to know what information can be sent for any car (as i will likeley have to shoehorn into the head unit as an existing device)
The CANDecoder I have is a Baoshijie for Ford Fiesta 2009-2014 and its MCU is a SWM181CBT6-50, is it worth trring to reverse engineer this unit, or as my vehicle has a HS CAN and a MS CAN, would it be better to build a open source can decoder (does such a project exist alredy)

As an update I ended up getting a RZ-FD09 SW:V0036.212.05-HS HW:FD-GD-0300

It's much better but still an incomplete mapping.
Illumination trigger trigger isn't working
Reverse trajectory isn't working
Button mapping is just odd in places.

I'm happy to make a schematic of this CANbus too if you are interested.

My goal now is to build a unit based around a RP2040 or 2350, that will work with both SavvyCAN for packet capture, and then work with canbox for the headunit
