How to Remove the Navigation Head Unit from a 2003 Toyota 4Runner
If you use a socket wrench you can easily have the dash apart in 10 minutes.
Has anyone integrated an ipod device in their 4Runner that doesn't have a cd changer? My HU only have a single cd player so the back of the HU only has 3 plugs instead of the 6 plugs or so that allows for an external cd changer (or ipod hook up).
