A1: Select based on your business needs.

1. Best value, best-selling: Choose "SD Connect C4 DOIP" – the most cost-effective option, supporting models up to 2024.
2. Latest Mercedes models (2025): Choose "Xentry C6 DOIP " or "Original XENTRY VCI C6" or SUPER MB PRO M6+ Pro, supporting programming and diagnostics for the newest models.

   Note: If you need a 2024 truck, you can contact us separately, provided you already have a 2024 or later truck certificate.

A2: All devices support it, but in different ways.

1. Basic programming (no online account required):
   a. Use DTS Monaco/Vediamo for offline operations (all devices include this).
   b. For example, "Xentry C6 DOIP" can modify speed limits, disable start-stop, etc.
2. Advanced programming (SCN online coding):
   a. Requires your own Mercedes official account (all devices require customers to handle account setup independently).
