Hello Everyone. I know this has been a question asked multiple times but when I search there is no solid answer or everyone has aftermarket amp. So before I go and bypass the amp I was going to ask for suggestions. Note: Everything was working fine before on stock system. Crutchfield was no help. Now that I research more I see the Beatsonic might have been the kit to go with. Vehicle is a 2004 LS430 as stated, non nav, factory amp, stock speakers. Anyway this is the setup I have or should I say crutchfield told me I needed:

Alpine ILX-407
Metra Dash kit
Axxess TYTO-01 Wiring interface
Metra Antenna adapter and extension

The harness is wired up correctly as seen. Wires not used in the 16pin as listed was Red, Brown, Light Green, Blue/Pink stripe, Green/Purple stripe, Orange/White stripe. Then on the smaller 14 pin I did not use the Orange, Black/White, Blue. Picture for reference on the harness below.



Everything was straightforward wiring wise. Everything powers up fine just no sound which seems to be the popular complaint with this system. I saw the videos of hot swapping...it works for a bit then it eventually turns off around 5 or so minutes...or if you turn off the vehicle you have to do it again, so as a solution it was only temporary. The only thing I got out of it was to see that everything is wired correctly. I saw a couple of posts where people have solved it but did not post what they did.

So to cover all my basis I just started doing basic trouble shooting:
Grounds - All good
Yellow - 12v constant - Battery Voltage on both sides of harness (Metra and to unit)
Red - Accessory - Battery Voltage on both sides of harness (Metra and to unit)
Blue/White stripe - Remote - Head unit section - Battery Voltage
Metra harness connected to Remote but not to TYTO-01 box - Battery Voltage
Blue - Power antenna - Battery Voltage (tested it anyway while I was there)

I also swapped the Alpine harnesses as my brother has an LS430 (not installed yet) also, mine being 04 his is 05. So I was going to knock out two birds with one stone (Identical head unit setups). So being that I built both harnesses I swapped harnesses to make sure, and also swapped the Axxess TYTO-01 modules. Both had no effect. Still the same...head unit operates fine but still no sound. At this point I am getting a bit frustrated and trying to figure out what to do before just bypassing the amp which makes the TYTO-01 that I was sold pretty much useless for the most part. If anyone has any suggestions or they have come up with solutions that would be great. The sub will be replaced at a later time and possibly door speakers. The sound quality was noticeably better for the few minutes it ran.

Thanks in advance.

 

Yep this type of thing comes up weekly. Yes the beatsonic will plug and play. I spent weeks testing and researching w my first 04, till I bought one. The one mention is that Beatsonic dosent allow front to rear fade, I believe. Small price to pay for adding all the head units technology into a great car.

FWIW I would also add a backup camera. If you look back under my user, I call out the trunk wire to tap and where to ground as well. You're already there if you are wiring the antenna adapter :-)

 

BeatSonic kit is what you need. At this stage though, I don't believe they sell it in the states but you can find a cheap one on Yahoo Auctions Japan. It's worth it especially for the dash kit which is OEM-quality. The Metra kit leaves a lot to be desired if you're concerned with OEM fit and finish.

FWIW, I'm running the BeatSonic kit on my non-nav/non-ML LS430.

 

True. i want to see if I can at least make it work since I already got all the metra stuff. I bought the stuff to bypass the amp worst case scenario which makes the tyto unit crutchfield sold me pretty much useless. It looks like beatsonic also stopped making stuff for the non nav 04 to 06 cars. But i believe the amp just needs a signal but i will need to look at a wiring diagram. Also need to figure out what wires are on the small plug if any of them trigger the amp. But I have seen a few threads where it looks like people figured it out but didn't post what they did.

I did want to wire in a rear view and front view, but I can wait on it for now. I just need to figure this out first. Does a great job playing music with no sound and charging my phone now.

 

Nice. Yea I will have to see. If it does go to needing the beatsonic kit I may just end up bypassing amp and using the head unit. But I would like to see if I can make it work for now before spending a day tearing apart the car and wiring the way the car I want to again. But the metra kit like you said is cheap...and I see why but its good enough for now. It has a slight gap up top but could be because of how more weight is toward the front of the ILX-407.

Thanks for the input so far. I may give crutchfield another call and see if I get another person that is more knowledgable...all the reviews for the TYTO-01 on the crutchfield site for no sound are for 04 LS430s lol. Makes me wonder if I connect my bros 05 if it will work....but I do not see much difference it would be.

 

I just looked on YAJ and there isn't much. Here is a good mounting kit, just in case https://page.auctions.yahoo.co.jp/jp...on/w1041405427 The SLA-23A is for the nav cars so I wouldn't use the wiring, just the install kit if you were interested. If you do end up needing the wiring harness, it's the SLA-24A that you want.

Keep us posted. There are times that I wished I had done a stand alone amp because I can't dial in my sound as much as I'd like but it still sounds pretty good.

 

Nice. Yea I am going to stick with the Metra install kit for now. Tried something new today...didn't work. But I need to figure out what the wires do on the small connector. As I recall seeing an old photo it looks like the beatsonic connects to the small unused connector Metra leaves disconnected. So it communicates with something I would think....or if I just run direct power to the amp and see what happens. Anyway I will prob test the voltages at the amp tomorrow. Just a drag to do all the stuff after work especially when I wasted part of my weekend trying to figure it out.

Thanks again.

 

So thought I would update. I gave up on trying to make the TYTO-01 work because at this point it is just frustration....if anyone sells that to you just don't even bother unless there is a trick that no one is sharing on the internet. I ended up bypassing the factory amp using the Metra 70-8117 harness (found it in a ML thread and it works on the 04-06 pioneer systems non ML also). Comes with an extra plug i did not use). I also repinned the harness to the speakers I had and I tried to keep the colors as close as possible to each other so no confusion later on. Hooked them temporarily into the RCA's on the aftermarket head unit and it works...but not right. So the speakers right now can be heard IF the head unit is maxed out. Just sounds like its on mute. Messed with the mute button and it is not that. Now I need to figure out why the sound is so quiet. The setup right now is speakers running off head unit, stock front and rear speakers, Tyto-01 module deleted as in unplugged and removed.....there is sound just super quiet, Not sure if it has to do with factory speakers or there is something I am missing. If I have time this weekend I have a spare set of old aftermarket speakers I may just test at the door to make sure that is not the issue.

But if any of you guys/gals have any input that would be great. Audio is not my strong suit but reading the wiring diagrams I could be missing something also.

Thanks

 

following, thanks for taking the time to write this all up. I'm debating putting a beatsonic sla 24a if i can find one along with a atoto s8 ultra or get a teyes cc3.

 

If someone made an alternative to Beatsonic they would make a killing...

 

At this point i would say get the beatsonic kit if anyone can find one for non nav. Save the hassle. I thought I could figure it out, but that has deemed to be a lie.

 

Even trying to find an SLA-24A in Japan is difficult. Remember, this is a 17 year old car now, minimum. YAJ currently only has one kit.

As this point, you're best bet for non-nav is to run a new amp entirely and bypass all of this together. There are still plenty of BeatSonic mounting kits for an OEM finish with your double DIN head unit...

 

Yea at this point that is what I am looking at Romanova....was hoping I would have some gap in between before having to do all this and hopefully solve an issue that seems to be a popular among the 430 community.

Anyway this was my updated wiring. Should be correct.

 

Helping a friend install on 2003 LS430 Non-nav....same problem with the install kit from Crutchfield. Hotswapping does work, but after turning off the car it stops working.
I cannot believe there is not a fix for this after all of these years.
So it all boils down to the amp turn on correct?? Is it that it needs more voltage for the turn on? Has anyone checked the turn on wire at the amp with the factory stereo? Is that voltage the same as what would come from the aftermarket stereo?
As you stated, it is so frustrating because if you hot swap everything works just fine.
Just checking to see if there are any updates.

 

I saw one solution in person where the guy had the factory head unit still plugged in and sitting in his glove compartment, with an aftermarket screen in the dash.
Didn't get to talk about how exactly it was wired up, im guessing he may have extended some of the wiring, but that's one option i guess
