OK, I am a brand new member as of today. This is probably in a forum here already so don't shoot me for asking but... I have a 2007 with dark khaki dash bezel and no nav. I am installing a Clarion NX700 NAV head unit, is there a way to modify the current dash bezel to accept my aftermarket unit or should I purchase another dash bezel and a double DIN install kit? Do I need a canbus interface? I have also purchased Infinity Kappa 3.5" for the dash, Kappa 6x9" for the front doors and Kappa 6.5" for the rear doors. Also 3 12" Kappa subs, with amps and an electronic crossover.
