There was one that fits perfect for toyota with double din decks. Its an Eclipes Navigation, Dvd, CD am/fm for $2000.00 kind of steep but is a sweet deck. This deck fits the factory toyota wiring harness, at least that was what I was told.
Just did web search for double din units for 4-gen 4-R. Result-nada, not even one hit, damit! I won't setle for standart size HU with empty space below. I'm keeping JBL until some one makes unit that fits 4-Runner.
I saw that one before, it does not fit our 4-Runners. Here is the sites quote after you search for install on that unit: "Installation Details for your 2004 4Runner SE

Kenwood DPX-MP4070 $349.99 "
You cant fit any aftermarket Double Din in 4 gen 4_R. I wonder why...
I would call a technical advisor at Crutchfield for detailed information as to why it may not fit. They are very helpful and they can “pull-up drawings” to determine what’s up. Sometimes it is something trivial. It’s a free phone call 888 955 6000
