I just installed the OEM unit on a 04. Pete's instructions are exactly right. The amp needs to go in the glove compartment as well...there's no room anywhere else upfront. One thing that is different is that I did not have to supply power to the antenna, the reception is perfect without it!
Hey Pete,
Great job on the nav installation!!!!
I just purchased a system from the oem folks, but I have a 2004 4runner ...do you think the installation will be much different?
thanks
Juan
