One of the many benefits of bTres is that we are always cooking up new things in our lab (my home office). Many of these things will be available as free software updates via over the air (OTA) updates.
Secondary display output
bTres supports dual displays. If your mmi has an HDMI input by way of a carplaykit or other device, it's as simple as plugging bTres into it to enable a second screen with all the pertinent information.
Track logging and many other cool location data based features are currently in discovery. I'm looking into accurate and quick logging GPS modules that I can use in the bTres. Once the hardware add-on is finalized, the software development will begin.
