Yeah, I think you are right, probably to much hassle to use daily. I first liked this unit because it required no wiring:That's an interesting product, but it seems to me not very useful for day to day driving. You've got to open the app and get connected w/Wifi. If you're in your garage your phone is likely already connected to your home Wifi.
Using the backup light for a power source works OK for hard wired cameras because they are pretty-much instant-on. With this, you have to wait for the transceiver to boot, and then your phone needs to "connect" to that SSID once it is detected by the phone. That could take a while. And you'd have to go through the initialization process every time you put the car into reverse.
So its not a clean, hands-free system. I doubt I'd use it routinely.

But there is no way I would want that unit sitting on my dash all the time. I contacted them about the possibility on using with a phone or other screen, but all I got was "we are working on it". That was a year ago.
