About us
Tested before sold.
Verified retrofit solutions for VAG vehicles.
Carsystems.eu is not a typical car electronics shop — and we are not an installation service. We specialize in developing, testing and validating retrofit solutions for vehicles of the VAG Group (Volkswagen, Audi, Škoda, SEAT). Every product offered in our store has been tested in real vehicles in our own in-house test workshop before it becomes available for sale.
Experience since 1994
Car-Systems has been active in the automotive electronics field since 1994. Over the years, we have evolved from classic car electronics and audio systems into advanced OEM retrofit solutions, adapting to increasingly complex vehicle architectures, software-driven systems and networked control units.
This long-term presence in the industry allows us to:
- Understand platform evolution across generations
- Anticipate common retrofit limitations
- Build solutions based on experience, not trends
Our location
We are based in Poland (European Union), operating from our own facility where:
- Products are developed and tested
- Retrofit configurations are validated
- Technical documentation and support are prepared
Being located in the EU ensures:
- Compliance with European standards
- Fast logistics within Europe
- Stable business and legal framework
At the same time, we support customers worldwide through our remote coding and online support systems.
Our philosophy: tested before sold
Modern vehicle retrofits are no longer "plug & play". They involve CAN / LIN / FlexRay communication, component protection (CP), software versions and updates.
If a solution does not work reliably in our own test car, we do not sell it. We do not offer theoretical compatibility — only verified retrofit solutions.
Fast technical support & remote coding
One of our strongest advantages is fast and precise technical support. Because we install and test our retrofit solutions in our own vehicles, we already know:
- Exact installation steps
- Required coding and adaptations
- Known pitfalls and vehicle-specific differences
We have also developed a refined remote coding system, allowing us to:
- Perform coding and adaptations online
- Support installations remotely
- Provide assistance worldwide
All remote support is based on previously tested configurations, ensuring predictable and safe results.
What we sell
We sell verified retrofit solutions, not just parts. That means:
- Tested OEM-based or OEM-compatible configurations
- Known behavior after updates
- Documented limitations
- Fast expert support
We don't sell promises.
We sell solutions that have been tested.
