I hope this feedback is taken in the spirit it is offered.
I will not buy this unit for a couple of reasons:
1. Price. As an add-on to an existing system, the price of this unit is more than what I paid for CentraFuse
2. Audio output. I already pass my audio from the laptop into my head unit. Why would I want to pass audio from the radio to the laptop via the audio jack? Why isn't the digital audio passed to the laptop via USB so it can then just be decoded/streamed/sent to the laptop audio out?
Other than the above I applaude you for your efforts and from all account what looks to be top-notch support.
