Just dropping into this thread, as I'm in a similar boat with our Japanese new-import 2014 S AZE0-1x (G2), sporting the terrible Pioneer Carrozzeria AVIC-EVZ05 (includes GPS & rear-camera).
This is the most entry-level EV we could afford, so lacks pretty much all the mod-cons from other models, eg. no big buttons next to the head unit, no steering wheel controls, etc.
When it comes to auto electrical, I'm a complete novice & a little out of my depth, so please be patient if this has been addressed elsewhere.
I've made arrangements with my mechanic/technician to help with the installation (as part of a package deal), but with the condition I source the parts myself & pay-per-hour for labour. Seems fair.
I'm looking at fitting a pretty vanilla Android 2-DIN head unit, and would like to avoid slicing & splicing the cables on the car (because it takes billable time & I'll want to remove the new HU when we sell).
I've tried all sorts of LMGTFY, but much is over my head or in Japanese.
Can't even determine if all AVIC range units have the same pin-outs, for when I try to reference a wiring diagram.
Living in NZ, shipping options are... difficult. Cost of shipping can often exceed the cost of goods and takes aaaages, so I need to get it right the first time.
TL;DR: what cabling & connectors (i.e. conversion dongle) would I need to mount the new aftermarket generic Android HU to the car-side cabling left behind by an AVIC-EVZ05, including appropriate mounting brackets? (I can 3D print some trim)
