Maybe find a dealer around to listen to some of the Hertz gear, the space8 and tweet are on a whole new level of what you mentioned (I am familiar with everything you posted) The bit1 is a dealer installed piece and I can pretty much guarantee that the manu won't go out of their way for a non dealer tech support. I have probably4 hours of time in just tuning a single vehicle with one, but out of the box it surpassed the 360 in sound quality. The 360 is a great piece but the bit1 is just that much better. Look for a dealer, I usually do not make recommendations for audio equipment, but I would state my whole reputation on the gear I mentioned... of course if properly installed.
Good luck with the find if you need to find a dealer let me know, I know they do not list dealers in the USA but I have a list on my other PC
