[@andrewtate2380]

Thanks for the video, it was instrumental in me ordering a T7 for my Honda Hrv. I hope everything goes smoothly on installation.

[@SimeonBartley]

I'm sick - throwing up and nausea. You provided a helpful lengthy distraction, so thank you. You also showed me how to improve the microphone situation. Channeling The Simpsons and AvE? Thanks :)

[@tiboladus]

Thanks from Finland!

[@SKANK44]

I agree, I bought an 8gb/128gb unit recently for my JDM Lexus ISF and the support from them was great

[@philwalker6444]

Thank you! Great video. Can we please have a 2 year review of the unit?

[@ZegaracRobert]

Large chip covered in paste is 4 channel audio amplifier, looks like old style AB class since pins are directly connected to outputs, if it was D-class, would have output filter inductors and cap network...

[@derekleclair8787]

Pumped about your setup. Have you thought of using usb vs coax into the minidsp helix? It’s a neat feature of that vs the cdsp 8x12. Thank you for the deep dive I hope you find the time to post your thoughts on the setup. I am interested in the 360 view, audio quality, and dvr. I hope android doesn’t mess with the output even over coax or spdif have seen some setups that the internal dsp does still effect the signal out of the digital outputs as well.

[@evankolpack]

Hey Derek, the DSP I have is a MiniDSP Harmony 8x12. I was looking at Helix options, but they don't support DIRAC or FIR filters. Being an audio junkie, these were important to me in a high-end DSP. Both the Helix options as well as MiniDSP support USB HEC audio. My MiniDSP supports up to 6 channels. You're correct that Android doesn't always like to play nicely at the OS/root level with digital audio outputs, so we'll have to see how that pans out (I'll definitely be doing a future video). If I can get the 6 discrete channels out via USB, I plan to route them to 6 virtual/digital ins on the DSP, which will feed the following outs (ins 1/2: front 3-ways, ins 3/4: rear fills, in 5: sub, in 6: blank). This way I can have separate control over fronts, rears and sub on my HU, closer to what you'd find in a stock system. This will be in addition to presets I can select from via the Harmony DSP wired remote. For a deep dive into the specifics of sampling rate and others pros and cons of USB HEC audio vs coaxial or optical digital audio out, I posted a thread specifically about that on DIYMA.

Hi Evan, thanks for the great video, im wondering how this setup is holding on, as i got one recently and the backlight of the screen just broke.

[@hvh7835]

Herman from Holland here..great obscure video😂 I ordered one and try to prepare my a-technical ass😅 On my volvo v70 Ive got a original fancy handsfree set built in...trying to figure out how it all can operate...needed to know if the t7 has a built in microphone that actually works...and now I know😊 I do not want to take the volvo kit out, but having two of these cockroaches in my car is just too much...I will try phoning with the t7 by disconnecting my volvo kit and will try the old handsfree set by disallowing phone permissions on android auto...shocking how little info there is on combining old carkit with a headunit😂

[@IchihanKuroson]

Can you show how you attached the noctua fan? And how has the performance been?

[@joecrush1118]

Could you check the amplifier IC chip, the chip that's just slotted in the back housing with the paste and see if it's a tda7850, 7851 or 7838? Thanks

[@stepancermak8914]

Hi, great video, I have a question. I managed to tight GPS antenna too much and hear crack. it is working but i would like to solder it back. do you know how to do it? is it difficult? Also is it difficult to open the EKIY unit?

[@samuel.p.7247]

Hello Evan Where do you connect the dash camera? Can you make a video about that?

[@americ6890]

Some other brand models reverse plug must plug in unit even if you don't connect rear view camera because the short two yellow wires are some kind of antenna I don't remember but you will loss WiFi or Bluetooth connection or will be very weak.😅

[@Sustainavore]

And one more question: do you know if you can plug your phone into it via USB and get all the same features as the heat unit would have over Bluetooth for controlling the phone? And would it use data tethered from the phone at that point?

[@nialrule]

If you plug the external microphone in and don't disconnect the internal microphone like you did, does the unit receive sound from both mic's?

[@Sustainavore]

How hard would it be to replace the 5g antenna mount, do you think? I want the ability to have hard switches for all of the wireless functions

[@Sustainavore]

I appreciated the Dr. Dre quote 😂

[@IDKWTFID]

Have you had any experience with newer style head units ? Any recommendations

[@bighigh69]

Great video. Thank you. If I already have a factory back up camera on my vehicle. Would the camera be plug and play with this unit?

[@EugeneOkumu]

It would. The RCA male-female pins should match for you to use the factory backup camera. If you want the 360 functionality though, you'd have to use the EKYI 360 kit. FYI they also have a front and rear parking sensors system that works quite nicely with the head unit.

[@bighigh69]

Thanks 👍

[@Sustainavore]

I'm also in Seattle. About to redo my sprinter van. If you were to buy a head unit today, would it still be this one or something else? Really appreciate how thorough you were with this video!

[@TristynRusselo]

Is there an SD card slot on the t7?

[@danielmanse]

Hi Evan! I bought this HU for my renegade but the firmware came with a birdseye app called 360 panorama, and is not working with my car's stock rear camera... Do you know if I can connect the rear camera alone into one of the pins in the birdseye plug? And if so, do you know which pin do I have to use? Thanks a lot 👍👍

[@evankolpack]

As long as your rear camera uses the same format (I believe these use component video, which is usually a yellow RCA plug) then you should be able to do exactly that. EKIY should be able to tell you which pin is for the rear bird's-eye camera, but it should also be on your wiring harness too. You should have one pair of wires + a trigger wire labeled in the online manual as for the rear camera.

[@TMCHL]

Ekiy using Joying Firmware which is quite poor you can't even turn on button lights via menu system ,wireless CarPlay has constant cut offs and CarPlay screen gets pixellated overall I do not recommend anyone Ekiy ...wish Teyes CC3 was a bit cheaper seems like its the most polished FYT unit so far .Thanks for the video P.s Orange ILL wire to ACC if you would like to turn on the Button LEDs :)

[@evankolpack]

Thanks for the tip. So the only way to get button backlight on is by hardwiring the orange ILL wire to ACC? I may install a switch cause I have some laying around. Honestly, I'm not too worried about lighted buttons, but it'd be nice to have. Also, don't care about CarPlay at all. Apple is notorious for not playing nicely with other operating systems or platforms, it's one reason I don't own any Apple products, and probably never will. I wouldn't expect any less from Apple regarding a generic Android based HU. That said, I would like Android Auto to work, at least eventually (firmware update) to extend the usable life of the HU (even after it's antiquated, it can function as a gateway for a brand new phone running all the latest and greatest). I've heard great things about the Joying HU, so that could be a positive if they're using Joying firmware....it could certainly be worse than Joying. I understand Joying does lots of updates and is kind of the "name brand" of these FYT HU's (along with Teyes). I'd like to avoid having to root this thing if I can, so I can probably live with Joying firmware for the time being. Unless you have other suggestions that work? I've heard it's very hard to root these new HU's.

[@FETTYNOP]

@@evankolpack My HengCheng FYT has a setting for button backlight but its based on time and never works especially with VPN maybe i will hardwire the ILL to ACC i have the pinout chart somewhere in this hard drive. Subbed for the additional storage for Prawn...music joke.

[@yazer79]

Thanks for the video. I have a question, if this unit only suppprts 4g why does it have a 5g antenna?

[@EugeneOkumu]

The 5G antenna should be for WiFi if I'm not wrong. Typically that's used when you tether the HU to a mobile phone.

[@TimRiker]

The non-removable antenna is labeled WiFi, not 5G.

[@russellhuston6481]

Ugh.. that was tough listening to all the adhd blurp tangents. Jeeezuz.

[@daijoubu4529]

Interestingly, there's another store, EKIY Global Store that sells a KK3 with a different UI, appears to be same owners as the Official store that sells the T7 (Joying - ugliest imo), there's a 3rd store EKIY AutoRadio that yet have another model T900 with different UI (Teye's inspired*)

[@wesleyvelroij4837]

I wish I didn't find this out: EKIY Global store, sells the same units under a different type name for a lower price. So now I'm asking price difference back from EKIY Official Store.... I ordered D7 from official store, which sadly hasn't arrived yet. But just find out, in Global Store they call it KK2. But of course it's the same.

[@markwoodfield791]

I know this is a year+ old, but hope someone will see this. I have been messaging back and forth with EKIY about installing a 10" T7 8G 128G in a flat panel in my RV. They refuse to work with me in any way and have asked me not to order. They claim their unit can't be mounted in a flat panel and won't even answer my questions about mounting locations for the cameras, extension cables, how many TPMS sensors can be supported, etc. I'm glad they helped Mr. Kolpack, but they have been completely unhelpful with my proposed installation.

[@dimitriospetridis1186]

Hi mate. I have a similar android unit installed in my Ford Fiesta MK7 2009 model. I bought it from a seller in aliexpress, its not EKIY but from my research the looks and the UI is excactly the same. Everything work fine except the steering wheel buttons. I did some troubleshooting and to sort this out i need to check the wirings. Unfortunately, the unit didnt come with installation instructions and wiring diagrams and the seller does not reply to my messages. If you have, could you please share with me any installation manual and wiring diagrams? Thanks is advance.

[@evankolpack]

Sorry man, I don't have any. My unit came with practically zero documentation, it was all online. Sadly, you may be out of luck if the seller won't reply. This is one of the big reasons to go with a brand like EKIY who, at least currently, has excellent customer service and will answer this kind of question. I'm guessing you could message EKIY and ask how to do it on THEIR head unit, and there's a strong chance that procedure/wiring MIGHT work for your implementation, but it's risky. If you connect the wrong wire to the wrong place, you could easily screw something up. ECU's are expensive. Sorry, wish I could be of more help. Good luck!

[@Stars-mk8ew]

does anyone know how to get engineering mode?

[@cyrusramsey]

Hi Evan, Thanks for the excellent technical video. Do you happen to have the Ekiy contact info?

[@evankolpack]

You're welcome. I just got in touch with them through the Ali Express contact option.

[@rsg5850]

Bought t7 8gb with ekiy dash camera with rear . Can't get the dvr rear camera to use as reverse camera when car is in reverse .

[@evankolpack]

Did you hook up the trigger wire to the correct place on the main harness? Verify it's getting +12v for your reverse lights? On my implementation the reverse trigger wire is right next to the main 12 +/- wire, but check yours.

[@rsg5850]

@evankolpack it was installed by professional radio installer and they said they did connect it with reverse tail light . My worry is that ekiy and even Saab unleashed KZbin video said the rear dash cam can do both reverse trigger on screen and recording, this may be not be true but I looked at another android unit mekede dashcam rearwhich also claims it does both. I wanted to get wiring diagram

[@EugeneOkumu]

I like how you live in your own world complete with your own take on words @evankolpack. 🤣🤣🤣 Not a very useful comment, but I stayed to the end of the video. I'm now headed outside. 🤣🤣🤣

[@ThePhilbox]

I've just installed a similar unit on my 2010 Venza. But.... When I turn the car on (not the engine) the unit is working. But when I hit the ignition the unit powers off. Do you know what the issue might be? After I saw the problem I disconnected everything but the power cable (second harness with RCA, 4g, GPS, etc.), to test and the problem remains.

[@evankolpack]

It could be many things, but I'd obviously verify 110% that the IGN power is wired correctly and actually receiving voltage. I'd also verify that the ground pin on the unit has a good low resistance path to vehicle ground on the body/frame/engine block. It could be some other external system causing it to shut down, but most likely it's a power and/or wiring and/or ground problem.

[@ThePhilbox]

@@evankolpack Thank you Even....I was looking at IGN power and wondering if some harness/adapter wires were wrong...But, I heard back from EKIY saying the steering wheel buttons wires are going to two plugs and I should cut one of them. Thanks for your reply. Appreciate it!

[@evankolpack]

@@ThePhilbox Glad to hear EKIY is still providing great support! It's EXTREMELY rare to find that with this sorta thing. Anyway, glad you got it sorted out. ALOHA! 🤙

[@ThePhilbox]

@@evankolpack Yes, they are and I'm very happy with the unit so far. Sounds good, snappy response. Just have to get the back-up camera working and Ill be 100% satisfied.

[@daijoubu4529]

Would a computer 80mm or 120mm+ fan fit instead of a screaming 40mm chinsy one lol

[@evankolpack]

It may fit, but you'd have to be careful about current draw. You may be fine with an 80mm, but I don't think a 120 would fit and you may draw too much current and blow to driver. Also, it may make more sound if you don't add a resistor to limit draw.

[@davidhsieh2761]

@@evankolpack My EKIY from the "Official" store is the variant with a slot for the 40mm fan, which store did you buy yours from? My mic had no leads but soldered directly to the board, I just cut the trace and If I want to restore it, I can just solder bridge the gap, the internal SIM cutout have also been removed so its no longer accessible unless you open it up. That large chip with a whole bunch of legs and thermal paste is the amplifier chip lol, I lucked out and got the better TDA7851L where the listing said TDA7388, the small square IC is the microcontroller (GD32/STM32 clone) The IC with the sticker on it is the NAND flash, mine reads 128GB (got the 8+128 also) and has no RF shield oddly, just on the other side with the SMA connectors. The large rectangular TSSOP IC is the DSP
