Hi there!
I really like the product itself and got one after the new firmware that connects directly to the car was released.
Sadly the bar didn't get any other firmware updates since then for me and there are quite some issues and lots of possibilities to improve the experience.
So I'd kindly ask you to open source the firmware and let others help out. Doing that will help all of us, the devs out there getting their fixes and features in and you by picking whatever fits your needs and get new releases out.
