I was wondering about this modification. My current audio system is the standard Isuzu one with the Tape Desk + In-Dash 6 CD Changer -- I would like to change the tape deck into something of a Navigation system/DVD/ while having a Rear View Cam auto-switch on when I hit reverse (sort of like the Infiniti FX series). Does anyone have any suggestion as to what components might I need for a project like this, or if better, someone to install this for me?
