I have installed this radio as a replacement for the Opel (Blaupunkt) CD 30 MP3. In addition, a phantom power adapter for active roof antenna, a mounting kit with matt chrome bezel (ACV) and LFB Adapter (N42 VX 902) were required. The radio can be so well integrated. LFB will continue to be used, on-board computer and system settings are unchanged controllable. Together with a Nokia Lumia 520 (with HERE + - navigation, coupled via Bluetooth) now has my almost 10 year old Astra H an almost contemporary infotainment system.
