[FYT Android Head Units] NootNootMF:
Just to add to Gonzo99's post, I also recently bought a T7 4GB-64GB from the "EKIY Official Store" for my JBL Camry. Here's a brain dump of my experience:

General comments:

Shipping was pretty fast - It took about 8 days from when I purchased, to when I got it delivered. They use their own shipper called UNIExpress - which delivered to my door at midnight. Pro Tip: Use https://parcelsapp.com/ to track rather than Aliexpress's tracking system. Gives a ton more information about the exciting world of customs processing.

All support communication goes through Aliexpress's message system. They are pretty fast at replies and they do try to be helpful as possible. Just type as simple as possible, and upload screenshots and photos when talking about wire harness and CANBus configs.

There is no EKIY public website (well there is a EKIY Australia site, but they just sell the external USB to wireless carplay box) to download firmwares.

EKIY has a YouTube channel (https://www.youtube.com/channel/UCIqkhYlXKjDbijIpZHfYdWg/about) which has a few videos that might be helpful.

They don't supply any installation instructions in the box, nor did they explictly say where the instructions where. Wierdly, they simply create an $88,888 item that shows the T7 installation instructions in the description (https://www.aliexpress.us/item/3256...4b693e5faGb096&gatewayAdapt=glo2usa4itemAdapt). Again, I had to hunt for this, they didn't tell me where this was until I asked.

My mistakes:

They didn't know that I had a fancy JBL sound system, so they included the non-JBL harness. To be honest, they asked me to remove my head unit and take a picture of the plugs, but I was too lazy, and just bought a JBL Canbus wire harness off Amazon.

I forgot to plug in the little Canbus wire jack into the back of the unit, so I was angry that the steering wheel controls didn't work - This is sorta their fault since they didn't give me instructions, until I found them myself.

Once I plugged in the Canbus jack, I was confused because I thought you could program the canbus buttons - thanks to this site I learn that Canbus systems often hardwire the volume/phone steering wheel buttons. Though there is an APK hack if you want to re-map them. (This is mentioned in the FYT thread https://xdaforums.com/t/general-fyt...s8581a-sc9863-q-a-mods-tips-firmware.4396339/)

There are two yellow camera wires, so there's a 50% chance you'll plug into the wrong one.

I bought the wrong factory GPS wire - The FYT thread said to use the SMA, but Toyota's use a HFC-III connector - not a big deal, they are like $7.

Their mistakes:

They should message you with the instructions so you don't have to google them yourself.

The image in the T7 instructions is not exactly like the model I have. For example, my model has a little CPU fan, but you have to plug a little power cable from another harness, and you need to turn on the Amp in the settings to enable power to the fan. (This is mentioned in the helpful FYT thread https://xdaforums.com/t/general-fyt...s8581a-sc9863-q-a-mods-tips-firmware.4396339/)

The instructions don't say you have to move the four mounting clips from the old unit to the new bezel. Otherwise the new bezel won't snap in to your dash. Took me 15 min to figure this out; and there is a non-zero chance you could break these when you are trying to remove them.

BIGGEST HASSLE: UGH: My rear speakers didn't initially work, and no amount of fiddling around with the Equalizer app and fade made them work. Didn't find this anywhere on the Internet, but in the Car Settings app (not the regular settings), there's a fade adjuster that sets sorta the default balance between front and rear speakers. It was set to max front volume. Anyway, now I get volume from the rear speakers, though if I make the equalizer fade 100% to the back, the rear speakers turn off. It's like the fade should only go to 75%, because at 80% and more, the rear speakers turn off.

The bezel is uhm.... kinda crappy. There's a small gap near the knobs, and the top part doesn't sit super flush with the bottom part. The silver part is more matte than chrome. The silver bezel clips don't really snap well. I knew this from several YouTube videos, but still...

The good:

Wireless Apple Carplay works well. A little confused on how the bluetooth handoff works, but we figured it out. The syncing process takes about 15 seconds.

The factory GPS connector works great. Thanks to the FYT thread for mentioning, though they should put a warning that every car has it's own GPS connection and to check first before ordering. Remember that if you 100% use CarPlay all of the time, then you won't really need this since iPhone's have a GPS.

The factory rear cam works fine - though I will probably replace it with the AHD cam because I want to use those fancy steering wheel graphics and better resolution.

Once I got the rear speaker thing figured out, the equalizer is a massive improvement over Toyota's crappy Entune system. Tons of configurations.

The internal mic - This gets lots of discussion - however, it seems to work OK at 55mph. To be honest, the factory mic in the old head unit wasn't THAT great, so I didn't bother plugging in the external mic - plus I think it looks ugly.

More Research: (I think these are answered in the FYT thread)

How do we change the garish default Android home screen? And it says km/hr in the widget?

How to back up the firmware since EKIY doesn't have a site to provide it?

How do I change the boot screen - don't want to see EKIY's animation all of the time.

How to make it launch the Carlink app when i start the car to automatically connect to my phone for carplay?

What's the best process for connecting another person's phone to Carplay? It seems very sticky to just one phone.

I'm going to look at seeing how I can remove the chrome border from the old bezel to the new one - maybe it can be glued and look nice.

Can we adjust the rear cam graphic overlay? Is it possible to calibrate it because it's too skinny now.

Most Interesting YouTube Video:

This guy has my exact unit and bought the fancy 360 Camera system. It's interesting to see what you can do with this head unit: (note that ugly screen - hopefully i can change it )
