2010 UK Prius T-Spirit (Nav+IPA) Android HU wiring query - reversing camera wiring

Hi there!
Exactly the same position as you! Same spec car, the lot! I'm using a similar head unit to the Xtrons and noticed the front door speakers weren't working. Further investigation found a mini amp under the driver's seat, but not the JBL.
So, all I need to do is add power to the amp?
Taking wire G3 on headunit (ACC red) and which wire is +AMP on the original loom? It appears that all wires on my 10-pin connector are used.
Many thanks

 

Finally making progress on this one, it may help someone with a NAV system, basic amp setup (non JBL) & Park Assist.
Still need tips with the mini amp power though, but shall get the multi-meter on it in a bit.

The REVerse trigger comes in to the NAV system from the IPA ECU using a grey 5 pin connector L42 and is the pink wire on pin 5.
This can be used to trigger the reverse screen on an aftermarket head unit.
Other wires on L42:
Pin 1 (Red) = Parking Brake Switch Sensor
Pin 2 (Black) = Ignition (10amp)
Pin 3 (Violet) = Speed Sensor (Some aftermarket head units and taxi meters need this)

The canbus from the IPA is:
Connector L41 White 20 pin connector
Pin 9 (Green wire) = TX+
Pin 10 (Pink Wire) = TX-

I will let you know if the Android system will accept these signals - Highly doubt it though!

IPA Video (includes reversing camera):
Connector L105 Blue Connector
Black single wire - However it is a GVIF interface.

This is the L42 connector

 

Hi!
I just got into a similar situation.
Did you find out the connection point of the amplifier?
Unfortunately, the camera is connected to the IPA ECU, from where you can disconnect a video signal
