Hi Martin,
To simplify your entertainment setup and enhance the guest experience, the best solution would be to invest in a universal remote control.
This approach allows you to maintain all the current functions like the Bluetooth adapter, DVD player, external HDMI source, TV Box for internet streaming, and HDMI output for the projector, while significantly reducing complexity for the users.
The universal remote can consolidate control of all these devices into a single, easy-to-use interface, reducing confusion and improving the overall user experience. Additionally, providing a well-illustrated, simple instruction guide alongside the remote will help guests understand how to operate the system effortlessly.
I hope this helps.
All the best,
