Integrating those with PDA/tablets can be a challenge, as most hardware can either take a single source or need more complex solutions to integrate multiple sources, especially if you want an instant on solution.
I found space for both PowerFlarm and TruTrak 57mm displays in my panel by getting rid of all redundancies, such as mechanical vario etc, as I found those to be significantly more useful and helpful than many things I find in other panels: multiple varios, compas, g meter etc...
