Hi Everyone, just thought I would share how I have upgraded the in car entertainment of my SC 430. First I did not want to replace or modify the dash in any way. I have seen pictures of people who have pulled the factory fitted stereos and replaced them with aftermarket kit and, just no.
So the driver behind all this was to see what could be made of the factory fitted equipment. I started the design around the Naviks kit and it was a case of what can it do and how can I enhance the car. There was no real primary objective, a case of doing it because you can.
Shopping list:
Zyxel N300 4G LTE SIM Slot Unlocked Wi-Fi Dual Band Router [LTE3302] (Amazon)
Google Chromecast (had in stock)
NAVIKS 2002 - 2009 Lexus SC 430 (Z40) HDMI Video Interface (NK-2300) (Direct from NAVIKS)
Rewire GPS Tracker (had in stock)

Heschen Timer Delay Relay H3Y-2 12VDC 0-3 Minute 250VAC 5A 8Pin terminal DPDT with DYF08 35mm DIN Rail Socket Base (Amazon)
Various cables and connectors as needed
Power:
Starting with the need for power, in the black box on the left in the boot is a permanent supply and neutral. I took a feed from that and wired it to common and NC of the relay. Positive is a bolted connection, neutral was a strip and solder.
Wired pin 18 and 17 from the Navigation ECU plug to switch the relay on when the car is started.
Why a relay?
The kit will pull quite a bit of current at start
The above kit won't hang off pin 17/18 of the ECU plug
For neatness
Time delay. Pulling that amount of power at engine start and while the power has not settled down I wanted to avoid.
Wired the NC from the relay and the neutral to the 12-way fuse block.
Result: I had a hard wired fuse block that was switched from ignition with a delay of 4 seconds.
Wired into this:
Reversing camera
Forward facing camera
NAViks
USB 12v x 5 port adaptor
Veba modulator
Wireless remote
Rewire tracker
GPS tracker:
All my vehicles have GPS trackers, rewire is a standard tracker just needing a SIM card and 12v. I also use gpsgate software as it is enterprise level software and yet they give you 5 free licenses.
NAVIKS:
This has three inputs:
HDMI, plugged the Chromecast into that, and as that needed USB, the 12v USB adaptor was used. Chromecast also needs internet. This is where the Zyxel N300 router comes in, using a 4G sim card, gives internet access and as the Zyxel is powered by USB, so plugged into the 12v USB adaptor.
CAR Reversing camera: Connect the reversing camera to this with the positive of the reversing lights.
AV in: Connected this to the front facing camera.
Has AV out. This was connected to the Veba FM modulator with that set to an odd channel (most FM channels broadcast on even channels). The Naviks sends the HDMI and AV in to the AV out connectors.
Selection button: The Naviks has a channel selector button on a shortish cable, instead of wiring all the way to the dash, I am using a wireless remote control switch.
Gives me:
Reversing camera
Chromecast, so stream my phone to the display such as spotify, netflix (only when parked), google maps etc.
Front facing camera
Internet access
GPS tracker
I have not replaced any part of the cars original OEM equipment
Not touched the dashboard
Other add-ons I am considering:
A NVR to constantly record both front and rear cameras where the footage can be downloaded to an Android phone.
Build pictures:
I did take them, but all you see as the project progressed was wires, wires and more wires. I did use cable tape to make things neat, just thought I would share what can be done.
