mega macs PLUS - the co-pilot for more workshop power based on Windows®

Whether starting or upgrading - here's what mega macs PLUS can offer:

- AI call for help - Direct access to technical support
- Future-proof - Diagnostics with the latest protocols
- Cyber security management - Access to OEM-protected systems

The best features at a glance:

mega macs PLUS is a reliable co-pilot for everyday workshop use that combines the strengths of proven Hella Gutmann systems with a modernised, intuitive user interface - optimised for mouse or touch operation. This makes day-to-day work in the workshop even faster, more convenient and more efficient.

mega macs S 20 is based on the Android operating system, whereas mega macs PLUS is based on the Windows operating system and therefore fits seamlessly into existing IT structures. Both systems are functionally equivalent: They use the same software interface, HG-VCI hardware and an identically structured licence model.

mega macs PLUS can be seamlessly integrated into workshop processes, is compatible with OEM systems and has a flexible licence concept which makes it the perfect choice for getting started, upgrading or switching - and is fully geared towards current and future vehicle requirements.

Your co-pilot for fast support

AI-supported on-the-spot assistance - efficient, precise and available 24 hours a day

When workshops use the innovative call for help function they receive support immediately - directly from the diagnostic interface and supported by artificial intelligence.

After a fault code query, the assistance call can be triggered immediately and all relevant vehicle data is then transmitted automatically. This eliminates duplicate descriptions and the workshop promptly receives repair instructions in real time.

If necessary, an experienced engineer can provide additional support by phone - for maximum efficiency and customer satisfaction.
