Yes...you would be able to "plug and play" with the new monitor. The "H-Cam" that I'm getting is made by the same people who make "Hitch-Cam". The only thing about having a different display, you'll have to have your local installer "mickey mouse" the system to have the display turn on when the H2 is put into reverse. (My local installer told me this...he thinks they'll be able to do this)
Anyway, the display screen is available here:

You can't buy the display from their site, you need to get it from your local car electronic dealer.
