Gen3 voice recognition is worthless anyway (I'm very good at different accents, to no avail "I beg your pardon?").Most likely you would be able to keep the reverse camera, but the voice recognition may be tricky.
They also completely ignored the issue with Gen4 (pre-facelift 2VN3 head unit) Bluetooth audio/control lag even when the cars were under warranty. It was a badly designed LiteOn Bluetooth module which was not able to handshake to correct audio stream protocol and defaulted to raw data stream. This is the only thing I dislike about my Gen4.They did NOT fix this same issue back in 2017 for 05/06 Acura owners. People were stuck with having to upgrade their NAV systems to 07+ units. I have zero sympathy for Honda. They did not fix this as far as I can tell the prior couple times it happened.
