Seeing how I will be starting the install into my 2002 Odessey, I would be very curious as to how they got the old unit out. I have the exact same setup you do (GPS, etc) so it should be similar. But since this model is new there is very little info on line about modifications to it. I like where you put the subwoofer but don't want to lose that space on mine. So it will be interesting to find some other place to put it. But any insights (no pun intended) you can give on your install would help.
