Yes — you can install iDoing on the Universal 7" double-DIN iDoing unit — needs a vehicle-specific bezel and harness for your car (Toyota/Scion shown) with a 11 min DIY job. Unbox an iDoing universal 7" double-DIN (QC 3.0 USB, GPS, Wi-Fi, CarPlay/Android Auto), T-tap or match a car-specific harness, retain USB and the reverse camera, then test-fit the bezel.
Overview
John unboxes a universal iDoing double-DIN: a solid 7" chassis (not a single-DIN screen in a double-DIN hole), a reset pin, a microphone, two USBs including a Qualcomm Quick Charge port, a generic head-unit harness plus a car-specific jumper, GPS/Wi-Fi, and support for Android Auto and Apple CarPlay. Optional TPMS is mentioned, with a listing in the description. On the car — a Scion tC — he twist-ties and tapes the color-matched wires (he recommends solder and heat-shrink for a permanent job), T-taps steering-wheel KEY wires, then powers the main harness (radio antenna, front/rear audio, dimmer, power) and tests boot before final assembly. He keeps the screen protector on until the unit is in. The boot logo can be set to a brand (he uses Scion). He retains the factory USB with the USB-B adapter, plugs USB-A, the radio antenna, GPS and Wi-Fi, the mic, and the reverse-camera cable, then shows reverse auto-switch. The Wi-Fi antenna is placed for range; GPS locked on from inside the dash. Finish is a clean Pioneer/Sony-style double-DIN look once the brackets and bezel are adjusted. Amazon is first with a tagged harness search from the description, then the iDoing product page and the AliExpress link he posted.

0:26unboxing this new unit it's called that the da da iDoing so iDoing is a really great brand we've been checking it out and I already count went through it so you get this little bezel right there
0:43this is a universal head unit so any car that has a double din this will most likely fit your head unit most cars even the modern cars have bezel x' where they adjust all that stuff so this is a
0:59universal kit oh look at this so we get this nice iDoing head unit it looks clean you get the little screen particular and yeah they got the little reset button
1:14really big kind of double din fool sometimes with the cheaper ones we'll only have a single DIN even though it's double din and that's the rear output it feels very solid cold to the touch and yeah few accessories you get within
1:29the box is zeroing in a microphone some USBs now you get two USBs one actually has qualcomm quick charging so if you ever plug your charger into your AC outlet you're like man this is really slow I'm only getting like one amps well
1:45this one will actually juice it up give you a little bit quicker chart definitely then you have your wiring harness that you plug into the back here so you plug this in and then you get your particular wiring for your
2:01particular unit so if you have a toyota by the toyota one I'll put some links on Toyota some links on general just harnesses for your car and it's pretty much like Legos okay maybe not Legos but it's pretty much like twist tie so you just match the colors most of the times
2:16or match the labels it's actually very simple this also comes with like steering wheel trolls in Wi-Fi GPS and the unit's actually very affordable it's about 200 bucks so GPS y5 HD touchscreen microSD
2:32slots so works it has all pretty much everything you want it actually supports things like Android auto and also apple carplay too so if you're into that you can do that with this another accessory that I want to mention is we also have
2:48tire pressure so yes it can if your car doesn't have tire pressures or if it does have it but it's like the really dumb one when it only shows like tire pressure basically when your tire is flat this one will actually show individual tire pressure so we're going to be testing that today - last question
3:06is does my reverse camera still work you can wire your reverse camera to work so if you have your stock wireless stock wired one you can have it to work or you can have add your own camera whether you want a camera in the front back rear unit side you can wire additional
3:21cameras so we're gonna get into the install alright so I just got everything wired now this is gonna be a quick job I have it twist hide and then I put black
3:37tape on it now you definitely want to do a heat shrink wrap and solder it for a more permanent solution but this is the way I did it because I generally go through a lot of Android head units because of a I kind of buy a lot of them so anyways I have a twist tie right here
3:53and remember if you want to have a good connection you definitely want to solder put a heat street heat wrap on it heat shrink to make it super tight and have no interference now with the Toyota ones or depending on yours you're gonna connect it to your existing
4:09harness so I have you know the 10 pin here then the 6 pin this is like power and audio and then for the stereo controls I have if you look right here this is key one so key plus key just key I think ground
4:25so these are the three wires so I could control the steering wheel controls if you don't have check with your check with your car to see what wires you need to tap into it's pretty a self
4:40explanatory because there's only three wires you just have to find those three wires and I just have a pretty much t tab to it there you go as far as connecting it okay so once you have your connectors plugged in I have radio so this is radio this is for the
4:56rear audio left right and then this is for the front dimmer switches included power so this is like the main harness I has with most of everything so if you once you have it all connected you plug it in here I know it looks really messy
5:11but if you works with if you're pretty organized it's not gonna be too bad it's you have to do it hands-on so I plugged it in here that's let's see what happens when I load it up so make sure you definitely want to test it there you go
5:33I stole the screw definite want to keep the screen protector oh if IR is up awesome you definitely want to keep this screen protector on there until you actually fully install that way it prevents any scratches so don't remove it just yet so it's booting up from what you can
5:48tell it says Android you can change this to whatever car manufacturer you want or you won't like your custom one in this case we're on a Scion tC so if you want to change it to a Scion tC you can do that yeah if you have a Buick you can change that so everything's
6:03working and it looks beautiful great interface you know you're gonna kind of on just test certain things but yeah it looks great check that out and it has the radio on deef by default it does have the radio
6:18on when you generally some of them have the radio on when you first boot it up so if you here like us like a radio sound make sure your radio app isn't open there ya go
6:33so other than that let's see what else we can talk about we have to add additional features so let's definitely turn off the car to several other things that you want to add is it's gonna be USB so I have a USB connector that's gonna allow you to retain your old USB
6:54yeah go ahead [Music] alright so I haven't done this came with a little USB it says USB B so we're
7:11gonna plug this back into USB B and this is gonna use the basically this car comes with its own USB down here so kind of be able to still use this original USB with this adapter so different cars
7:28have different adapters so I also linked this adapter and other adapters if you were interested next off we have a USB a and we want to plug that in so that we can have it in this case where we have this USP a right here
7:43alright so we're gonna plug this in straight up right here it's just like Legos there's a clip right here you wanna plug it in make sure it you have that you hear that satisfying click and
7:59lastly there's the radio antenna either the GPS and Wi-Fi antenna will also plug in and there's also the microphone so make sure you plug that in now you probably notice this little thing right here this is the reverse camera and for Reverse it's it's gonna be this cable
8:17right here let's plus turn on the car let me kind of show you once you plug it in so if you threw the car reverse if you can step on the brake right there sir
8:32it's gonna automatically pop to the reverse and you're gonna have that that's nice reverse screen so it's gonna be this camera right here yeah that's pretty much it so things are set just
8:49have to wrap it up make sure it looks nice and clean and then we can show you how it looks so I'm just gonna wrap it up all right so we have it kind of wired this is how it's gonna fit with this so
9:05you can do a little test fit no I look like something like this and of course you can adjust these brackets and stuff but yeah it looks really complete this is exactly how a pioneer or Sony head unit will look like so if you're interesting something like that that's how we have right here I also did the
9:21liberty of also plugging in the Wi-Fi antenna which is this kind of like hopper looking thing right there per the customer and he wanted the Wi-Fi in the dash so he can and we want the extra range he just throw it out here
9:37wouldn't that be I mean you could range me throw it back here so I did that as well the GPS antenna is actually really strong I had good look of us having it right here and it picks up intended problem intended signal no issues alright so we have the iDoing head unit
9:54looking really clean with a clean interface if you guys are looking to buy this once 200 bucks I'll show you about 200 bucks links below where you can get it yes you can there's a bunch of features if you have any other questions links also below on where you can find
10:11other head units and harnesses this is a universal head unit so will fit pretty much any car universally that's why it's called universal other than that this is the iDoing 8.0 octa-core look looking
10:26good pace out
