Multi-Zone Tutorial (work in progress)
This thread is a tutorial on configuring openMobile for multi-zone use. It is based on the default skin. And it is under construction and subject to change (error correction). I am building bit-by-bit over the next couple of days.
First, your operating system needs to use extended desktop mode for multiple displays. Multi-zone operation will not perform properly without it. It's an OS thing. Make sure your touch-screens are all calibrated and working as intended. Ensure your audio devices are all registered and functioning.
Multi-Zone (MZ) is the scenario where your car computer drives more than one audio/display hardware devices. It is NOT multiple independent computers. For the purposes of this tutorial, the target system is installed with 3 displays and 3 audio devices. One is the on-board built-in audio device and display output. The other are USB video adapters and USB audio devices (headphones). The on-board audio drives amps that drive the vehicle speakers. The following diagram depicts this setup:
When you start up openMobile, it will auto-configure some zones for you. Each detected screen will be numbered starting from Screen0. Audio devices will be named according to the OS name, and a "default audio" (typically the on-board OS default).
To begin, select the 'Settings' button from the main menu and you will be presented with various settings options. Select 'Multi-zone Settings'.
You will then be presented with the currently configured zones. Note that I have already re-named the 2 zones that OM created for me upon startup.
At this point, you can either select the "Menu" button at the bottom, or long-click the zone you wish to work with, giving you the following pop-up panel
