Hardware Development TEYES CC3

!!!!!HISSING SOLVED!!!!!

So, because this was my first time with replacing a head unit, I made some uninformed mistakes. Unfortunately there are no instructions for car specific model installations so it required some research. BUT I hope this post can be used to help others down the line. For anyone using a Teyes CC3 and using the OEM Bose amp from the 2013 CX-5 car, make sure you do the following, a little history of my process is also included:

The unit was shipped and received with two Power harnesses. One harness had a blue cable labelled "AMP-C" while the other harness had the blue wire labelled "AMP" and ALOT more connections like RCA etc. The harness with the AMP-C wire also had the Antenna assembly photo'd below with no RCA connectors:

What caused the hiss was using this harness originally, attaching the AMP-C on this harness to the AMP-C on the audio interface harness photo'd below:

This was a mistake. the amp was receiving power and signal through the AMP-C connection i soldered giving the amp more power than it could deal with essentially feeding the amp a line level signal hence the hissing.

So after much troubleshooting, i noticed that the other harness that had the blue "AMP" wire had a number of RCA inputs (RCA are normally passive signal)! And I had a spare RCA harness that came with the unit (also photo'd above next to the audio interface harness)!

Once I soldered the AMP-C from the audio interface harness to the power harness's AMP wire, I plugged in the RCA cable harness to the power harness as well(FR, FL, RR, RL). The RCA harness plugs into the back of the CC3. Photo below:

Now came the ANT car connection, the power harness with the RCA Plugs and "AMP" wire did not come with this, so I had to cut the blue connector (marked with an "X" in the photo above) from this harness and solder it to the ANT lead on the other. See photo above and below^^^

Once everything was assembled into the car, it worked. It just worked. I was able to bring power conditioning in the CC3 all the way back up to 60 and it sounds crystal clear.

Thanks for info! Unfortunately I have a bit different harness and could not copy that.. Could you measure the voltage level now turning your amp on? Just thinking could I just reduce the voltage level to achieve what you have. At the moment I have 10.8V switching the amp on.

I imagine it will be around 10 to 12v. Can't check at the moment since it is POURING outside. Can you send a photo of the harness that you have? What trim Pajero is it?

Here is my harness assembly:

I also have relay connected (between blue and brown wires) so amp will not turn on before ignition is on, because someones have had issues of battery draining without relay cutting out amp. But that should not create any interference to amp, I believe.

There are tens of different variants of original head unit and thus different connectors on them, and on mine I dont use that antenna plug as car antenna plugs straight to CC3. Blue wire on that antenna plug is already connected to that other blue wire (connector on right side of the pic) that turns amp on. Also all RCA's are unused.

I dont know is there fault on diagram or something, but on that plug that has the blue wire turning amp on, it is named "ANTENNA-POWER" and next to it black wire is named "AMP POWER ON". At first I connected brown AMP wire to that black "AMP POWER ON" wire and that did not turn the amp on. Only when connected to blue "ANTENNA-POWER" wire, amp turned on:

I already tried to reduce voltage level with couple of diodes I found, those only reduced voltage level ~1.1 V and it did not affect to the hissing noice at all. But I dont know so much about CAN bus systems, is it more about the waveform than voltage level that matters in this system?


Here is also the instructions Teyes offers (the second red NOTE at the bottom):

This variant head unit needs 2 modifications to - 1 - Make the original AMP turn on to have sound. 2 - Install relay to turn amp off when accessory power is off to prevent power drain. Special thanks to Tobias from New Zealand who refused to give up on his install! NOTE: Around the world the...

Hey all, any of you having an issue where the radio wants to play no sound for about a minute after starting car? Doesn't matter which input is selected

 

[mattybigs246]

I also have relay connected (between blue and brown wires) so amp will not turn on before ignition is on, because someones have had issues of battery draining without relay cutting out amp. But that should not create any interference to amp, I believe.

I see in the instructions they mention a Green/Red wire as opposed to a blue wire for the relay switch install.

I dont know is there fault on diagram or something, but on that plug that has the blue wire turning amp on, it is named "ANTENNA-POWER" and next to it black wire is named "AMP POWER ON". At first I connected brown AMP wire to that black "AMP POWER ON" wire and that did not turn the amp on. Only when connected to blue "ANTENNA-POWER" wire, amp turned on:

Alternatively it states that the blue AMP-CTRL wire must be connected to the pink ANTENNA ON wire from the green plug block. Which i assume is from the OEM cable going to the amp. I wish I had this car in front of me to get a good look...

I factory reset my CC3 and then updated to the May update and I can't open the "app drawer" at all. It looks like it wants to load then just crashes back to the home screen with no message. Anyone else experience this?

In instructions there are two different variants of the head unit, so wire colours and connectors varies too according to variant. Also the power harnesses that attach between head unit and car harness varies too and has different wire and connector colours. So my AMP-CTRL wire on head unit harness is brown and it connects (via relay) to car harness that has green connector and pink wire on it.

I've just upgraded my cc3 to the may 2023 update. Now bluetooth doesn't appear at all on any device searching for it and android auto now is no longer wireless. Any help appreciated.

I have tried different forums, including Australian ones, but not much help on this matter as this is not so common setup yet. Well not on FB, yet.

Yes, I had MMCS with integrated GPS.

My guess, less a Teyes issue, more a canbus cable issue (ie you're different than the norm )

Yep, I have had in mind to buy new amp to replace original and get more noice Well, maybe I can live with the hissing sound until that

Did you read a post, a couple pages (?) Back about a fix for the hissing, different car, but probably the same problem, (incorrect wiring of power cables) ... Post included a few pics

Yep, that post is the one I replied in the first place in this matter (if you mean the same post I'm thinking of you are talking about) And that made me wondering can I fix it if it is related to Teyes/harness. And here we are

Hopefully you get it sorted

I only scanned through the posts, not really taking much notice of who was following/participating...

I suppose you really need to get a pin out diagram for your specific headunit, and help (?) from someone with electronics / audio experience verses programming experience ...

The wiring looms will most likely be "off the shelf" supplies from the people supplying the stereos, with very little (quality) mix n match knowledge...

If "you're lucky" someone out in the community comes up with the solution - but nothing gets changed by the sellers
Because as posted previously it's just "cookie cutter reselling"

@jamdwan i also lost android auto after May update, it clearly has to do with WiFi shutdown which the log claimed to solve I can see on my phone how it momentarily connects when carlink shows connected and everything resets.

Did anyone downgraded the OS from May to March update? March version worked like a charm for me

My march update worked perfectly. As soon as I was in the car, android auto worked wireless everytime, never dropped connection at all. Updates usually bring more upgrades, or slight variations to make things even better. What the hell went wrong here to completely lose bluetooth from the device!!!! It's the most basic function. Praying the June update works to fix this stuff up.

Has anyone got the different reverse camera views working with the Teyes AHD reverse cam?

These used to work with my OEM camera but when I installed the AHD reverse camera, it just stays in the ultra-wide angle view even if I press the buttons for the different views.

I have a normal CC3 installed on my Honda Civic LX 2019 btw.

Any thoughts?
