It's really great that you did this project and I am eager to build it and use it in my 9-3. I noticed that there have been significant changes over the last few months, e.g., completely new Bluetooth module. Do you think the current hardware design is pretty much the final version, or is it likely to change? I'd hate to order PCBs and parts and then discover it's obsolete before I even finish building it. :-)
