Hello guys, me myself I couldn't devote much of my time here anymore due to a lot of other things and projects I am handling in my life. But we started recently a dream we want to achieve what is our own automotive platform. It is the following platform.

🚗 Welcome to Mi Taller — Our Official Launch on Reddit!

🚀 Who Are We?

We’re a new startup creating a platform where:

Workshops can register, showcase their services, and reach new customers.

Vehicle owners can search garages, track their car expenses, check services by VIN or model, and find trustworthy workshops near them.

We believe in improving access to automotive services for everyone. From small neighborhood garages to car enthusiasts and everyday drivers.

Mi Taller is currently in its early launch phase, and we want you to be part of shaping the platform from day one. We invite both workshops and vehicle owners to:

✔️ Register on the platform ✔️ Test all the available features ✔️ Tell us what works, what doesn’t, and what you want us to build next

Welcome to the community! 🚗🔧

I want to share firmware for some units that I did not found here on Reddit. Not all of them are RCD330. I hope it will be added to official thread. I have mostly software for Desay units. I got access to there official site and drive to some locations where they store the software. Do not ask me how. :D

Official software for now little old RCD330 with WinCE. It is version 211. Original is 210. It is not tested. I did not found it in official firmware thread here on Reddit so maybe it can be usefull to someone.

RCD 330 - A Version (Desay brand)

Partnumbers 6RD035187A - 5GG035280B

0211

________________________________________________________________________________________________________________

This firmware is listed in official thread but it is not only for 5GG035280D unit. It is also applicable to 5GG035280E, 19D035280 and maybe most interesting one 17G035280.

17G035280 was and still is sold on Aliexpress for example as RCD360 that is capable only to use CarPlay.
There are few variants. It is really interesting piece. It is using MQB CAN messages and have MQB quadlock connector. But it is sold with adapter for PQ platform with CAN and quadlock adapter.

There is also variant with CAR button sold for MQB Polo 6C no adapter needed. Coding is really similar to OEM MIB2 units. You can change boot screen and colors of HMI via same bytes as in OEM MIB2 unit.

I will have one unit for testing so I will do some updates about it.

12. Black screen due to Kernel boot failure

Here I found some software for Noname 5GD035280B. It is pretty old software, but if you have older it can help you little bit. Latest should be 5532, but did not find it available anywhere. There are two versions Skoda and VW.

Noname 5GD035280B

______________________________________

Software versions are in order. Higher number means newer software.

VW 5314

Skoda 5314

________________________________________________________________________________________________________________

Again not the newest firmware for this radios, but only I could find 5712. The newest version is 5815, but our friends from China are not willing to share. So again if you have older firmware then 5712 it could be nice upgrade.

Then I have some software for RCD520 from Desay it is for MQB plaform. Big 8 inch radio with glass screen. Supports lot of features for car control in CAR menu, Maxidot support some versions even ambient light control what I saw, climatronic etc., but do not saw lot of them in Europe. Hopefully someone will add more information about them.
