Love your attention to details
I can offer my free translation services-I can translate from Eng to Polish. Polish people would appropriate good dash cam with Polish txt.
I'm a Linux Engineer and I don't mind getting my hands dirty with your firmware and provide translation in the format you need it to be.
I can also sign up for a beta test but you have to prepare yourself for VERY detailed reports!
Your new camera sounds intriguing. I'd like to purchase one of the early units, when possible.
I'm not looking for a "free" beta-test. However, I know that by getting an early production run it's bound to be a little rough on the edges. This is what I value, because you'll be in a mode where you can make improvements in later runs.
