No boot sequence, no parking sensors, no radio, etc... I tried system reset (hold radio power button for 30s) and disconnecting the battery for ~1hr; neither had any affect.
I took the car to our local indie who checked all the fuses (none were blown) and said their diagnostics tool wasn't connecting to the HU, so said they'd need £300 to remove the HU and dig deeper to diagnose. That seemed ludicrous, so I removed the HU myself and didn't notice anything odd (annoyingly, our indie won't let me drop off the HU for testing). I noticed there seems to be what looks like a fuse visible when the main cable is removed (see circled area in pic). If so, I'm thinking this might be worth checking.
Given a used replacement HU from eBay can be had for under £200 i figured maybe the next step should be to get one of those and fit myself. Would also be useful to know if alternative part numbers can be used; e.g. a newer HU model?
Anyone have any other ideas what I could try before doing this and/or able to point me in the direction of someone who might be able to code a replacement HU in (again, my indie won't do this for 'insurance reasons')? I'm in south west Surrey.
Thanks in advance.

Thanks for sharing…looks like yours is the CIC headunit….mine is the NBT headunit and has no such fuse. I disassembled the whole thing so I’m sure.
