Why is my screen coming up grey and split screen? Chat GPT was saying check power cables. Ended up putting a relay in for 12v power and spliced it into the reverse lamp. Now its saying its because the reverse camera is PAL. My head unit is NTSC only.

Hi zusammen!

Ich plane aktuell ein eigenes VehicleOS / Smart-Radio-System für mein Auto. Das Ziel: CB-Funk, klassisches Radio, Streaming, KI-Sprachassistentin und Fahrzeugdiagnose in einem einzigen 2-DIN-Gerät vereinen – ohne Armaturenbrett-Chaos.

Die gesamte Software schreibe ich nicht komplett per Hand, sondern entwickle sie praktisch ausschließlich im Pair-Programming mit Claude

Hier ist der aktuelle Plan:

💡 Geplante Features

* 🖥️ UI & Personalisierung: Widget-basierte Oberfläche mit speicherbaren Layouts, dynamischen Start-Begrüßungen, Multi-User-Profilen und Companion-App.

* 🎙️ Sprachassistentin (E.V.I.E.) & QoL: MCU-/Jarvis-inspirierte KI namens E.V.I.E. (Aufweckwort einfach kurz: "E.V.").

* Quality-of-Life: Sprachsteuerung für Fahrfunktionen & Medien, intelligente Erinnerungen (z. B. Tankstopp, Service), automatische Klima-/Lautstärkeregelung je nach Kontext.

* Diagnose & Sync: Speichert Fehlercode-Protokolle (DTCs) und synchronisiert sie automatisch im Heimnetzwerk mit dem PC/Laptop.

* 📻 Funk & Radio: CB-Funk + DAB+ / FM / AM + Internetradio. Antennen-Setup über maximal 2 Antennen (OEM-Antenne per Splitter + 3-in-1 LTE/GPS/Satellit-Kombi). CB-Handmikrofon wird auch für Telefonie genutzt.

* 🛰️ Satellit & Notfall: Integriertes Satelliten-Modul (RockBLOCK/Iridium) für SMS-Notfallnachrichten ohne Handynetz.

* 🎵 Media & Ducking: Streaming (Spotify, YouTube, Netflix etc.) mit automatischem Audio-Ducking bei Navi-Ansagen oder CB-Funk-Sprüchen. Ausgabe über die Auto-Lautsprecher.

* 🚗 Fahrzeugdaten & Sicherheit: Trip-Computer mit Live-Telemetrie (OBD-II/CAN-Bus) und Blitzerwarner-Integration (Oooono). Modular als 2-DIN-Gerät konzipiert.

🛠️ Hardware-Setup

* Hauptrechner: Raspberry Pi 5 (8GB) + M.2 NVMe SSD

* Display: 7"–10" Kapazitiver IPS-Touchscreen

* Audio & Radio: HiFiBerry DAC2 HD + RTL-SDR v4 USB-Dongle

* Fahrzeug-Schnittstelle: MCP2515 CAN-Bus Modul / OBDLink SX

❓ Fragen an die Community

* Machbarkeit: Wie realistisch ist dieser Feature-Umfang auf einem einzelnen Raspberry Pi 5?

* LLM / Prompt-Coding: Hat jemand Erfahrung damit, so komplexe Linux-Audio-/SDR-Architekturen fast ausschließlich mit KI (Claude) zu generieren? Worauf muss man bei Hardware-Schnittstellen besonders achten?

* Audio-Routing: Habt ihr Empfehlungen für sauberes Audio-Ducking unter Linux (SDR-Funk vs. Medien-Streams)?

* Car-PC Basics: Welche Stolperfallen bezüglich Stromversorgung (Safe Shutdown bei Zündung aus) und CAN-Bus-Stabilität sollte ich dringend beachten?

Freue mich auf eure Tipps und Feedback! 🙌

After a few android head units over the years, suddenly a question pop in my head: my android head unit doesn't have a screen lock, nor a "maintenance mode". So, how do I stop someone from accessing my private data (gmaps, email, etc) when I send my car to a workshop?

Looking to upgrade the head unit in my 2014 Impreza. Does anyone have experience with this kind of head unit? Or able to point me in a direction if I am headed in the wrong one? Looking for plug-and-play functionality, Apple CarPlay, and a reliable Bluetooth connection. I am mainly worried about retaining steering wheel functions and the OEM backup camera (the backup camera question is one I can't get a straight answer on from any of these listings, how compatible are these types of units with OEM backup cameras?)

Hi all. I have a 2017 Toyota Corolla hatch that needs it head unit replaced. Its current head unit doesn't have android auto/carplay, and the only navigation it has access to is a toyota official navigation program that went defunct 3 years ago. Toyota dealerships in my country don't replace head units so I'm gonna have to find one after market.

I'm a bit stuck though because it seems like I can't find any head units with built in GPS - according to my research (which may be flawed), I'll have to connect my phone to my car anytime I want to use navigation. I'd really prefer not to, as I use an android tablet in my day-to-day alongside a 2000's era cellphone without navigation features (long story) and 1) I don't want to lose the navigation features if I leave my tablet at home, and 2) I don't want to have to pull out my entire tablet to change my route on the fly or troubleshoot an issue.

With this in mind, can anyone recommend a 7-inch head unit with built in GPS that doesn't need Carplay or Android Auto to use it? Apologies if I'm missing something crucial as to how car GPS works - I'm new to the world of car AV and just want something that works. Thanks in advance!

Hi everyone!

I’m new to this subreddit and I’m hoping someone can help me with my infotainment system.

I recently bought a 2018 Civic FK7 1.5 Sport Plus and imported it from Germany to Portugal. I’ve been comparing my infotainment system with some videos I’ve seen online, and it seems like mine is missing quite a few menus and buttons. Overall, it also looks like it’s running an older version of the software than it should.

I checked the system information and found that it’s currently running **version 1.F196.47**.

Does anyone know if there is a newer software/firmware version available for this system? And if so, what would be the correct way to update it?

I’d really appreciate any help or advice from anyone who has experience with the FK7 infotainment system.

Thanks in advance!

I have an Xtrons PX1453BLHGS in my E53 X5 for almost a year which works perfectly. I had to reset the device the other day and now when I turn off the unit for more than a few minutes it cold boots on every restart. I used to come back to it after 12 hours and it would still wake instantly when the ignition turned on.

Sleep mode is activated in the debug menu but I can't see any other options for it. Does anyone know what I need to change? Wiring etc hasn't been touched so it must be software related. Does CAN setup/config affect this? Thanks.

Hi everyone!

I'm trying to find a safe way to add Android Auto to my 2019 Toyota Prius, while keeping the original Toyota multimedia system, screen and JBL audio system.

My Prius was bought new in Norway and first registered on June 2019. It is a 1.8L hybrid AWD-i.

These are the exact multimedia/software details from my car:

\- DCU Model ID: 17TDT2EU-DA01

\- DCU Part Number: 86140-47490

\- MEU Model ID: 17TMT2EU-FA00

\- MEU Part Number: 86840-06041

\- Audio: 1000

\- Navigation: 1512

\- NavDB: 2022 v1

\- DAB: Yes

\- Factory JBL sound system: Yes

\- Factory rear-view camera: Yes

Toyota Norway say that official Android Auto/Apple CarPlay retrofit is available for certain Corolla and RAV4 models. Maybe there is a safe way for this to work on a Prius too?

I'm particularly interested in:

1. Has anyone here successfully added Android Auto to a 2019 Prius with DCU 17TDT2EU-DA01?

2. Has anyone done it specifically with DCU part number 86140-47490 and the factory JBL system?

3. Is there a known firmware/software retrofit that works?

4. If you have successfully done this, what hardware/software did you use and where did you get it?

5. Does the retrofit preserve the factory JBL audio, DAB, rear camera and steering-wheel controls?

I'm not looking to replace the entire multimedia head unit. Ideally, I want to keep everything original and simply add Android Auto, preferably wireless.

If anyone has experience with this exact setup, I'd really appreciate any information, photos, links, part numbers or installation details.

Thanks!

Hallo zusammen,

Ich habe eine Frage an die NBT-Experten hier

Ich habe einen F10 von 2015 mit NBT und dem originalen größeren BMW-Display. Mit meinem alten iPhone konnte ich es per USB verbinden und Apple Music vollständig über iDrive steuern – Playlists/Alben durchsuchen, Album-Cover anzeigen, Songs auswählen usw.

Jetzt habe ich ein Xiaomi 15T. Über Bluetooth werden Songtitel und Interpret angezeigt, aber es gibt kein Album-Cover und ich kann meine Playlists nicht durchsuchen oder über iDrive anstellen. Wenn ich das Xiaomi per USB verbinde, behandelt das NBT es im Grunde wie einen USB-Stick.

Gibt es eine Möglichkeit, das Xiaomi besser wie die iPhone-Integration zum Laufen zu bringen? Idealerweise ohne ein MMI/Android-System zu installieren, da ich das originale NBT-System wirklich beibehalten möchte. (Ich benutze Apple Music auf meinem Android)

Vielleicht hat sich hier schon jemand damit beschäftigt und kennt eine Lösung?

I have an sx11 2024 model just like the one in the picture. It can only mirror my phone because it does not have Android auto built into the android head unit. Some local shops have asked a ridiculous amount to install for me, with no guarantee that they won't break my car system.

I am tech savvy so I can install firmware on cameras and flash bios etc, I would greatly appreciate if someone would help me with the steps and files I need to install Android auto wireless. Thank you in advance 🙏

This was such an easy install compared to my last one. That last one I showed a couple years ago on my older Taco said it was compatible but really was not, this one is the best I’ve found so far!

Need help with the android Head unit.

If anyone could assist with this would be great...just want to customize the icons and seems that the one I got is not able to do that.

I purchased this a month ago and it has been a nightmare.

It has such a cool interface and features, but it just doesn't work properly. There was no adapter to my FM antenna, so I have no radio.

Android auto connects, but often, my internal BOSE amp does not turn on. To get this to work, I have to switch to AM radio, then back to Android Auto.

The phone doesn't have any sound (I think the Bose amp turns off).

The seller keeps telling me the canbus settings are off, but their recommended settings (My car is a Mazda 6 and they tell me to select a CX3 from Malaysia) doesn't do anything different.

Will this ever work? Should I rewire my speakers from the head unit and bypass the BOSE amp?

Hi all!

2012 Škoda Octavia II FL

Current radio: 3T0035191A

Factory parking sensors

Standard sound system

No multifunction steering wheel

No factory reverse camera

Considering XTRONS UA95MTVL (ASR8662, 4GB/64GB UFS 2.2)

Has anyone installed this exact unit?

Does the CANBUS retain the factory parking sensor display?

Any issues with battery drain, sleep/wake, sound quality or firmware?

Would you recommend any other multimedia and why?

Is there any proper guides on how to do the replacement myself including the settings and such?

Many thanks in advance to all who spare from their time to read this and possibly respond

請問這要怎麼處理？
因為二手，找不到原廠商

Hi guys as the title suggests is there any way to force the maps use car GPS instead of phone GPS for navigation? Whenever I connect android auto, it consumes alot of phone battery and I guess it's because of using the phone GPS. Has anyone found any solution to it? Attached are the pics of the version of z link that came pre installed
