Sorry can't help with this one.
The Toyota Technical Information Systems (TIS) is where this info is available. It costs $10 for a day's access to their data.
http://techinfo.toyota.com/
The Highlander data is not all there yet.
You have access to TSB's, Repair Manual, User Manual, New Features, Wiring Diagrams.
They have changed their format over time.
They used to post just a series of pdf files by section. It was focused on the lowest access speed and sliced at 1 to 30 pages of sub paragraph levels.
Within the Acrobat Reader you could save these files to your computer.
TSB's and other stuff is still in this format but the repair manual is in a different format. If you do not have a print to pdf capability you can print what you see to paper but not save it as a pdf.
I use a plug in called pdfMachine to allow me to select "Print" and select the plugin to save to a pdf file.

Still it is an official Toyota info site
Would suspect it is like most Toyota's and you pry off the fascia some how using a nylon pry tool to get access to the screws that hold in the radio.
Tools....
