[FYT Android Head Units] gottahavit:
After a lot of reviews and reading I just ordered a 9" Idoing with CanBus for my 2018 WRX with Harman Kardon. A lot of positive reviews from WRX owners, but not seeing a lot of love(or hate) for the Idoing hear on XDA. It's nearly identical to the Joying, but Joying will not support the HK system in my car.

The system is an android 10, UIS 7862 4+64. https://www.aliexpress.com/item/32955093508.html

I'm curious what custom options I have in terms of UI, ROMs, Root,, apps?

I'm guessing from what I read(or lack there of) ROMs are a no go, but what about root and other customization options?

Sorry long time rooter and custom ROM user for android phones and tablets, but total noob to android head units.

I have a Kenwood with wireless android auto in my old car and was going to move it to this one, but absolutely hate Android Auto almost as much as I hate mirrorlink in the stock HU in my WRX(shame on you subaru). Also the kit to install it from crutchfield cost nearly as much as the android unit and canbus shipped from china, so figured i'd take a chance.

If it doesn't work out I'll go with the kenwood, but really hopeful this will be a winner. I spent a lot of time on chat with them and they are extremely responsive to questions(really like live chat) where a question to Joying took 3 days to get a response.

I know there is little chance the 4G module will work in the US(IDoing says it works with tmobile) so expecting to use wifi tether with my phone with native apps and pretend android auto doesn't exist. Other option is put a spare phone with sim permanently connected to USB, but unsure if USB tether will work.

I will keep reading, but any thoughts or pointers are welcome. Just don't tell me to replace my HK system, I know not everyone likes it, but I love it ;-)

FAIR WARNING!!!! After a year with no issue, My IDoing fried itself today!! I was driving and it shut down and for about 1 minute I could smell burnt electronics. This was a plug n play install so no cutting, no splicing, no soldering. I am in the process of seeing what IDoing will do for me, but I expect the answer is nothing since it is now over a year old.

Update: Well at least IDoing is talking to me. I pulled the unit out today and put the Stock stereo back in(UGGGH). At least nothing else got fried.

Update 2: So they are saying that they want me to pull the unit off the mounting trim and mail it to them and they will send me a knew one. I'm assuming this is going to cost me 100 bucks in shipping and need to wait a month or more, but it's better response than I expect.

Update 3: They "say" that once I give them tracking number for the unit, they will ship new unit and all i have to pay for is return shipping(30 dollars)

Final Update: Well it cost me a lot more than the USPS web site inferred (85 dollars), but they shipped a replacement the same day I gave them the tracking for the return. New unit showed up in just over a week, Unit looks new installed in less than an hour and all works great, software looks to be nearly identical except the AA software that it came with support wireless out of the box, so small bons. Unfortunate the original unit fried itself after a year, but considering it was out of warranty I have to commend Idoing on how they handled this, now I just need to remember all the tweaks I had installed ;-)
