I ran all the usb cables to the centre console along the middle, there’s two cuts in the metal frame allowing you to run it all straight into the console.
I got 6 usb cables there for both android units lol.
@khuong Got my audio overhaul done (I'll make a separate post with my install notes). With respect to the CAN bus, here's where I landed. I have the 2002 SC430, which is a little different than the later models. I successfully used the ASWC-TOY-LEX adapter. In *my* configuration, it works great and all the buttons do what they need.
Step 1) got the ASWC-TOY-LEX adapter working with the new head unit by just plugging into the 7-pin connector. Worked perfectly.
Step 2) bridged the busses as shown, including the resistor network. Both the ASWC-TOY-LEX and top nav unit stopped working.
Step 3) Unplugged the ASWC-TOY-LEX and the built-in nav bus started working again.
Step 4) Clipped the wires from ASWC-TOY-LEX bridge to the other bus and it started working again (but the Nav stopped) I've concluded that something in the bus isn't quite right still, so I'm giving up. The steering wheel controls work great and they're much more important than the old Nav screen.
So, basically I can't get top nav bus to work with the ASWC-TOY-LEX added to the can bus this way.
I gave up on the bridge of the network. The top nav is dead and I guess I'm OK with that since my new head unit is lightyears better than my 2002 Lexus nav.
Yeah, not sure where to go from here. The Toy-Lex 6-pin plug basically takes over the network between the Gateway ECU and the radio. And with the radio gone, there is no brain left to tell the Multi-Display to open/close/tilt.
My electronics knowledge doesn't extend far enough to figure out how to keep the Gateway ECU in the system and get the data to the Toy-Lex. Going to think on it a bit before changing anything.
The solution might be to go over to the PAC SWI-RC-1 product since it doesn't use any of the radio/Gateway pins or connectors.
I am "almost" done with my make-over. I say almost because while the sound system itself is up and working well, I did something wrong inside the doors. Oh, and I misplaced the cigarette light cord when I was wrapping up the wiring for the headunit (not a big deal would have gone unused anyway).
My goof-up concerns the door lock switch. They unlock by the interior lock switch, but no longer lock using the same switch(have to manually lock the doors when exiting). There isn't even a sound of trying to lock. Perhaps I didn't get the plug in correctly. Not sure.
If anyone has done this, and fixed it, I would appreciate some guidance as to what goofed-up thing I did. I read through some posts and tried locking and unlocking several times, waited overnight and came out to find the system self corrected. Strange (from my experience) but true.
Lots of others have done a better job of documenting what they did for stereo redo efforts, so I will just make a list.
A list of what I replaced, and with what:
Multi-display screen -- Lilliput high-brightness monitor (fed using HDMI cable from headunit)
ML (Pioneer) Headunit -- Xtrons TQ700L Android double din headunit - 4 GB RAM, 64GB ROM, lots of bells and whistles. Only using a few of them..
ML Amp -- Kicker 4-channel amp - channels 3&4 bridged for a sub. located in same spot the ML amp occupied
ML Woofer -- Pioneer 8" shallow mount. Fits perfect, was even able to use OEM mounting ring
ML Door Speakers -- Pioneer Premier midbass/tweeter component set. I put the silk dome tweeter where the 4" ML speaker was located - it was too big to fit in the metal dome ML tweeter spot.
ML Back seat speakers -- not used, I personally don't care for speakers behind me.
OEM Speaker wiring used.
RCA cables from headunit to amp - run along passenger side.
Back-up camera mounted above license plate, between lights. Power tapped from back-up lights as well as using them for the trigger to switch the headunit to auto display the rear camera view.
Currently using an Axxess ASWC-Toy-Lex steering wheel control interface. It works, but to use it I had to give up the push button activated door to the Multi-display. Someday I will try out my PAC audio steering wheel control box as it doesn't require use of the radio plug that makes the Toy-Lex no longer support the door opening/closing by switch.

Reason: Lock problem fixed.
I do suggest the PAC .. i think your mileage will be better than mine with the buttons, as my car has more buttons on swc. I actually ended up adding resistors to every button on swc module + disconnected it entirely from the car, and used the clockspring wiring, (which was the same one that the PAC wanted from the SW column) advantage is now i have 8 buttons total - which i use for both the android HU's in the car.. lol 2 for top, to switch between waze/cameras.. and the rest for the main HU where old radio was to control the audio/volumes.
After looking at my failed ML amp, I decided to check impedance for the speaker channels at the amp.
My best guess at cause of failure:
The PO basically ignored the failure of the speaker surrounds. The decayed and missing surrounds couldn't keep the speaker cones properly aligned. Based on the impedance I saw on a couple of the speaker connections at the amp, my guess is the speakers shorted out and that fried the output section of the ML amp.
One of my boys proved a direct short will kill an amp when he "did in" an old-school Sansui receiver.
Hence my advice - if you want to keep your ML amp alive, make sure you take care of your speakers.
What brand and model did you purchase?
I believe the ML sub is 16ohms…not sure it matters much.
I have read many times on the forum about the 16-Ohm woofer. And there's a high likelihood I'm beating a dead horse, but I thought a tiny bit of clarification might help anyone searching for a replacement,
Based on my car (later model years might be different) -- the woofer has a dual voice coil design with each coil being 8-Ohms. So it could be wired as a 4-Ohm woofer (voice coils in parallel), a dual coil 8-Ohm woofer, or a 16-Ohm woofer (voice coils in series).
Based on the wiring diagram for a 2002, it's wired as a dual 8-Ohm voice coil woofer.
That said, I don't think it's easy to find dual 8-Ohm voice coil woofers, so this why I thought I might be beating a dead horse.
Red - One wire connecting those 3 points in the connectors.
Orange - One wire connecting those 3 points in the connectors.
Blue - Put 1 - 68 Ohm Resistor between both the Red and Orange Wire.
This will retain the NAV Functions - Door Open/Close. Had a tornado warning here earlier today, so I haven't had a chance to test it with the Axxess TYTO Module with aftermarket Radio - I'm certain it'll work but that'll be tomorrow or weekend.
RED Connect the 3 pins ORANGE Connect the 3 Pins 1 68 Ohm Resistor between the two wires.
@khuong ,
Are these connectors at the back of your nav display unit?
if I wire them as such, then I can remove the nav display unit and still have the close/open/till buttons working?

I'm not @khuong , but he's referring to the connectors on the back of the radio/headunit. The radio door does not need the connectors to function, as the door mechanism has its own connector.
The Nav unit does not have a separate connector for the door. There are other threads that refer to removing and retaining a board from the nav unit if you don't want the nav unit but you still want a functioning door.
His drawing makes use of the unused radio connectors (after installing an aftermarket radio) to keep the nav door functional without buying something like the Beatsonic box. . Basically his works outlines a a simple but functional LAN "master" (the 60-Ohm resistor - replaces the 60-Ohm resistance in the radio unit)), and the wires that provide a LAN signal pathway for the Nav unit door.

Hey oneround is correct, that drawing is for the radio.
If you want your NAV Tilt/Open/Close to still work -- after you remove it, you must retain the pcb board that the original NAV unit uses, depending on the year of your car, that'll either be a single board with 3 connectors, or a large board with 3 connectors + daughter board.
The threads are linked in this thread to the posts, but basically you take it apart, keep the board, and tuck it connected behind your speedometer (plenty of room).
However you'll still require some way of retaining the NAV commuication to the ECU (via the resistor or if you a beatsonic)
