Yes, install wasn't too bad, but you do need to remove a few things to get to it. Follow the G35 install guide on Youtube.
Plays most movies i've downloaded, MP3s and TV works. Sat nav is sweet and gets good signal even in the city. I put the GPS antenna in the passenger pillar to keep it out out the way.. to much crap on the dash.
I would recommend buying a better TV antenna tho, because it is digital you want a better signal than the one that comes with the Eonon units. I bought one that sticks to the inside of the windscreen and it was at least 20% stronger signal strength.
