Seat Leon MK3 MIB1 Apple CarPlay/Android auto install

I’ve always wanted Apple car play for my lean (had it 5 years now) and I recently saw a place down south fitting some “box” to enable it. Decided to look on AliExpress and found this nifty little kit. Cheap mod in comparison to having to retrofit a full newer head unit for double+ the price and way more effort.

Very quick guide on installing this android auto/Apple CarPlay module for my 2014 Leon. Filmed with my phone so just recorded important bits for anyone who might want to do this mod.
I saw a review from a mk7 golf which had different connectors which I’ve highlighted in the video.
Also there’s an option to “use original Bluetooth sound” in the boxes UI, so you connect them both to have sound and the CarPlay/android auto enabled. I touch on this in the video but played around more after filmed.
It doesn’t come come with any instructions but I just followed the pin settings on the tricker it came with (which was different to the advert) and to get the car to/from CarPlay and back to the cars main UI you just longpress “Car” on the infotainment.

Thanks for this video. I bought this module using your link in the description and it arrived yesterday. I attempted to fit it this morning but i was using the wrong coloured leads and thought I'd been sent the wrong kit (Says Porsche on the box, and no instructions included). Found your video again which helped me select the right coloured lead, and select the pins correctly. All seems to work, but i only got sound for a minute or two and then it cut out. I've disconnected it all again and will have another go when ive got more time on my hands. Wish they'd included instructions, I'd have had it done hours ago!

[@TBagger489]

Yeah I can imagine without any tutorial it’s not the nicest jobs when leads come with different colours! Are you IOS or android? I think I made ref to it but I’ve also connected my phone via Bluetooth through the cars original head unit, then in the options select “get audio from Bluetooth” or something like that. Also in Spotify I’ve turned off the car play mode, for some reason it didn’t play audio properly when in car mode. 🤷‍♂️

[@davesrc_crawling8349]

@@TBagger489 thanks for the reply. I'm using Android Auto. With those settings, does the SEAT system need to be in 'Media' function to play the music? It doesn't seem to play through AA as I expected it to, and I think that might be why. Or am I incorrect? Appreciate the help so far 👍

[@TBagger489]

@@davesrc_crawling8349 yeah I have mine set to Bluetooth as the output in the media settings. Pleasure to help that’s why I put this up - once you get it working properly you’ll never need to mess about with it again, mikes has been flawless since installing. :)

[@davesrc_crawling8349]

@@TBagger489 ok, that makes sense now. Basically all Audio passes through the media channel over BT, while the visual stuff is handled by the module. Next challenge is to wire it in neatly somewhere so I can still use the glovebox 🤞

[@TBagger489]

@@davesrc_crawling8349 yeah, that’s how I understand what I’ve set up. However when it plays text messages etc back this is still coming through the CarPlay module, rather than BT (I think) just to further confuse things. 😂 yeah I’m going to try knock a hole in down there to slide the module into. I’ve got a reversing camera I’ve never installed I’m going to try into the new harness, won’t tuck it away till I’ve done that.z

Hi, I have a 2015 leon with Mirorlink only, so thanks for the tutorial and short review of this module. I would like to ask you a favor, could you test if it automatically switches the UI to the original Seat UI when you park? Because of the parking assist. Or is it necessary to switch the UI manually when parking? thanks!

[@TBagger489]

Hi, no it stays in the CarPlay mode when parking. Switching back is easy but it doesn’t do it automatically. There is some options in the UI for aftermarket camera on/off but I’m not sure what it does - nothing so far 😂

[@jooles88]

Hi Thanks for posting this - I have a Seat Leon 2014 just purchased the same unit as yours - seen some other videos specifying the part No mine found out is "5F0035858A" is your the same - Just hoping it's compatible.

[@TBagger489]

If it has the unit in the glove box it will work, don’t think it matters the version other than that and being mib1/2 👍

No he entendido lo del bluetooth para las llamadas

[@TBagger489]

@@jonninyro9739 Hola, estoy usando un traductor, así que disculpe el idioma. Cuando instalé el nuevo módulo no tenía sonido. en la configuración de los nuevos módulos tengo que seleccionar la opción "usar bluetooth original" y luego conectar mi auto a la manera anterior con bluetooth también. Según tengo entendido, todo el audio viene con la conexión bluetooth. Después de una semana con él, todo funciona impecable.

No me oyen en llamadas por android auto, pero el comando de voz si funciona

[@TBagger489]

@@jonninyro9739 Pruebe la configuración de bluetooth o cámbiela en su teléfono para no usar carplay para el sonido, use la entrada de bluetooth. esto lo hará como antes pero controlado por la pantalla carplay.

Is it possible to Connect CarPlay by the usb cable (not wifi) Connect the iphone to the OEM BT and in the box select the option “ use original car BT for the sound” ? So i get the CarPlay wired, but the audio by BT?

[@TBagger489]

@@davidga6272 yep it has a usb port so u can plug in that way, whilst it will still use the Bluetooth audio. The first time connecting I had to use the wired option before wireless started working. Not sure if I was doing it wrong or it needed it to sync? But yeah this works

[@Filip-B22]

Today I installed the module and after that on the odometer displays problem with the tire pressure indicator. Maybe someone else had such a problem and knows how to solve it?

[@TBagger489]

No issues here, to be sure it’s module related I would unplug it and see if the issue is resolved. Sounds strange and I can’t see it being connected but best testing to be sure.

[@kaysontee]

Do you have pins 2,3 and 7 on and the rest off? I have the same leon as you touch screen as you

[@TBagger489]

Yup, but I think from memory the latter ones doesn’t make a difference, so having 7 on or off didn’t matter. Can’t remember for sure but only 1/2/3 made an impact on our version 👌

Is the radio am/fm automatically turned off when turning this module on? Doas the am/fm radio work when the module is turned on...? Thank you!

[@TBagger489]

So you can flick between the input modes as normal in the normal seat UI, I haven’t tested the radio whilst using the module but I’m 99.99% sure it still works since the cars audio comes from the original cars input source (Bluetooth) meaning all the original stuff works as normal. Hopefully I’ve explained this right, I’ll double check next time I’m in the car. 👌

[@danieljohne8655]

When listening to am/fm radio and then switching to carplay for google maps - will then the radio stop or just smootly play all the time? I just want to use the normal radio while using google maps :D Thank you so mich!

Hi I have a 2014 Leon and for some reason when I plug this in the screen is zoomed into the top right of the apple play is there. A fix ?

[@TBagger489]

Have you checked the sliders on the back to ensure they are set correct for ur model? I think mine was 1 off and 2&3 on. The rest didn’t make a difference but it should come with a diagram showing which model needs what pin setup.

[@filipstojmanovski1274]

Do you fix the sound mate i have the same car and i want to order the same product can we get in contact pla

[@TBagger489]

Sound works fine, I selected the option in the UI to use cars original Bluetooth audio then connected the car the way it used to he connected. So for me the sound from my phone goes to the car via the original Bluetooth sound and the CarPlay screen is done over WiFi - works a charm. Happy to help if you go ahead and buy it. 👍

[@darylm8342]

Apparently you can get a ami to aux cable which tricks the mib1 so you can select the input to have sound no problem
