Spoke to Nav Tool today. Good news for all of us! Here's what they wrote...

"Hi we are releasing one in end of April with price of $399, it will have inputs for 4 cameras and HDMI for smartphone mirroring

Thank You

My buddy was an early adopter on this, very glitchy. Not worth the price tag IMO

 

I'm curious as to the version he had. This model is not available until end of April.

 

It's already May where is this device?

 

Interested in this as well. I know Beat Sonic was coming out with something similar, but haven't heard any updates in a while.
