I want to replace the factory radio in my newly purchased 01 4runner. Does anyone know of a good reputable place to find the aftermarket din that has the storage deck below?

metra electronics makes a dash pocket for u.
part # is 88-00-8000

check out my double din navigation in the photo gallery.

I would try Crutchfield.com. If you have a local CarToys, they have storage decks that fit perfectly into most cars.
