Dude, did you look at those steps? The NAV systems and the non JBL and the JBL radio all go in the same location in the 4runner. It's the same way to get to the radio for all 4th gens.
Ok thanks. Wow that's a good bit of work to take out the radio. On the Volvo I push a tab on each side, some bars pop out and you pull it out by the bars. Then it just unplugs. I was hoping for a more simple way.
