My land cruiser still has the original head unit and an aftermarket pop out screen (Very 2000's) and I'm thinking about swapping them both out for a new oem toyota one.
I'm not looking for any crazy features other than Bluetooth and green backlighting to match the other dash lights.
I want to know if it's a do-able swap or if anyone has attempted this before.

I would be interested in that old one if it works and you are selling it.
 
Not sure which one is aftermarket, it looks like they both say Toyota on them.
I have not seen those units in play on 100-series here in the US, so not sure if any of the swaps previously detailed here would be of value to you?
I do love reading these threads though, I will probably never swap my head unit, I will just read threads about until I the end of time...

The Pictures I have attached are pictures of the oem head units I am thinking on installing and NOT of my current setup in the land cruiser.

Ah, that makes much more sense! No wonder you want to install those! The deck in the first picture looks very nice, as it plays mp3, WMA has USB, and it looks like you can control your phone from it (assume via Bluetooth?).
2nd unit looks nice and expandable as well! Plus Nav, plus DivX.
How much do these units cost in the UAE? Assuming you are in the UAE...

I am in the UAE, These units cost pretty much the same as they do in the US but something like 10 or 20% cheaper because here we have 3rd party Toyota parts suppliers pretty much around every corner and you can get an okay price if you haggle But what I'm planning to do is to just get one out of a wrecked Toyota.
My main concern is if it is a straight plug and play setup and if anyone has had experience with these before.

Do you have part numbers? I have never seen these in the US - but that does not mean they were not offered here!
If you dive in, I would love to see how easy (or difficult) it ease to swap these in.
Thanks!

Don't have part numbers but I'm sure these headunit's are in Many Toyota's like the Hilux and Yaris, One place I am sure that they exist in the US are in Scion FRS's and Subaru BRZ's. They are basically the same unit just rebadged.
I found a forum where someone swapped it into his FJ Cruiser New toyota head unit. - Toyota FJ Cruiser Forum
 
It's pretty common to put the Scion head units into 4th gen 4runners. They're a direct plug and play application there.

The scion units have built in amps, so it would require some wiring/modification to get one to function properly in an LC/LX.

It looks like you could source the wiring pigtails from the same toyota that you're planning to pull the stereo from and splice them (or repin them) while doing the amplifier bypass that @RobRed has detailed very well on his website tlcfaq.

As for amp bypass, are you talking about this: Replacing Your Audio System: Overview or this: Stereo Wiring: Land Cruiser / LX 470 (1998-02)
?

If there is a better write-up devoted to amp replacement, I would like to read it. I think I am becoming obsessed with reading about stereo replacement...

Let me dig through my list of "notes" and see if I can find some more info about completely bypassing the amp using as much factory wiring as possible. I'll post up relevant threads/posts as I can find them.
 
Ok. I cannot find a coherent all in one thread that fully outlines how to 100% bypass the amp, so with the disclaimer that I've never *actually* done this and don't know a lot of variables such as impedance of the OEM speakers nor impedance at the output of the Scion stereo I'm going to attempt to do that for you here. I am going to assume that you're trying to install a Scion stereo, as that's what we are discussing in this thread. Doing this for an aftermarket stereo would be eerily similar. All pin numbers are taken from the 2004 LC Electrical wiring Diagram, it's all I have available. If you want pin outs verified I would gladly do that if you can source me the correct year/model EWD.

You will need to use a 2nd harness to connect to the Scion stereo. The cheapest/easiest to source would be Scosche Reverse Harness This will plug into the Scion head unit to get the power in and the signal out of it. If you have the 20 pin connectors you will need to pull 4 short runs of wire, because that connector uses a common ground for the signal from the stereo to the amp and the Scion unit uses a closed loop to each speaker.

You would then have two options. You either remove the pins from the OEM plug and insert them into the correct location in the Scosche plug, or you would cut the OEM harness and solder/heat shrink (or your preferred method of connecting) to the Scosche harness. I have not verified that the OEM plugs from a LX/LC will fit into the Scosche harness.

Here are the connections for the 20 pin LC harness:
  • R36 pin 1 to Scosche yellow
  • R36 pin 2 to Scosche orange
  • R36 pin 8 to Scosche gray
  • R36 pin 9 to Scosche white
  • R36 pin 11 to Scosche red
  • R36 pin 13 to Scosche blue
  • R36 pin 18 to Scosche purple
  • R36 pin 19 to Scosche green
  • R36 pin 20 to Scosche black

The pin out for the LX 20 pin connector isn't exactly complete over on the "Stereo Upgrade" page so you would need to verify via LX FSM before making connections.

Now, back to that tricky common ground that we discussed earlier. Your 20 pin harness wiring won't have anything to hook to the FL-, FR-, RL- or RR- on that Scosche harness. You will have to pull 4 wires from the stereo area to the OEM amplifier area while keeping track of which one has been hooked to which corner's - output.

Good news is that if you have the Nakamichi system then you won't need to pull any additional wires.
Here are the connections for the 22 pin LX Nakamichi harness:
  • Pin 1 to Scosche yellow
  • Pin 5 to Scosche blue
  • Pin 6 to Scosche white
  • Pin 8 to Scosche purple
  • Pin 9 to Scosche green
  • Pin 10 to Scosche red
  • Pin 11 to Scosche black
  • Pin 13 to Scosche orange
  • Pin 17 to Scosche gray with black
  • Pin 18 to Scosche gray
  • Pin 19 to Scosche white with black
  • Pin 21 to Scosche purple with black
  • Pin 22 to Scosche green with black

Now that that's all connected up, we have a means to plug the stereo in and can move on to the connections at the OEM amp. These pin numbers are assuming that the LX amp pin outs are the same as the LC amp pin outs posted on tlcfaq. I have no means to verify this information but haven't found anything stating the amp connectors are pinned in any different order. Due to the different outputs on the Nakamichi system I cannot believe the amp pin outs are the same for it; however, I have no means to verify this as I don't have the LX wiring diagram. Here you would, as mentioned on tlcfaq connect:
  • S7 pin 3 to S6 pin 7.
  • S7 pin 2 to S7 pin 9.
  • S7 pin 10 to S6 pin 13.
That will get the power/ground into your head unit.

Moving on to the signal wires we would connect
  • S7 pin 5 to S6 pin 2
  • FL- wire that was added to S6 pin 9
  • S7 pin 6 to S6 pin 1
  • FR- wire that was added to S6 pin 8
  • S7 pin 13 to S6 pin 4
  • RL- wire that was added to S6 pin 11
  • S7 pin 14 to S6 pin 3
  • RR- wire that was added to S6 pin 10
Now after all of this pin swapping and wire pulling we have successfully created a path from the battery/ignition switch to the new head unit to power it on. We've also created a path from the head unit to the speakers in the doors while fully bypassing the OEM amp under your seat. There are no Subwoofer outputs on the Scion head unit so it would have to go unused.

A few notes:
  1. If this doesn't make sense to you, please don't attempt it. There's no reason hacking your wires just for the sake of hacking your wires.
  2. While they are OEM and look quite nice, those Scion head units are under powered compared to aftermarket units. Most are 10-18RMS per channel.
  3. The OEM speakers aren't the best
  4. If using an aftermarket head unit, it's really not much more difficult to pull new wire to all 4 doors directly from the head unit.
  5. If I've mis-typed or gotten anything wrong please let me know and I'll edit the post.
  6. I don't see the true benefit of going through all of this hassle for not much of an upgrade, in my opinion.

If you could get me the electrics wiring diagram for the vehicle that those stereos come out of, and the electrical diagram for your model of 100 I would gladly check to see if it's easier for you. I see that some of the FRS/BRZ pioneer head units have a separate amplifier so they may be much simpler to retrofit.

That says a lot right there, thank you! When I checked out the link in the FJ forum, they were talking about throwing down $1200-$1400 for these head units. I like OEM, and I like Nav, but not that much! Plus, I did not realize there was no signal for sub-woofer...

Thank you for writing this up. If I found a good head unit from a wreck, maybe I would do it.
