I wanted to update this thread with some pictures just in case someone was looking for information on Sirius and the factory Navigation I thought I would post some pictures.
First of all they install the antenna (XM or Sirius) inside next to the rearview mirror. While this is a cleaner install (and easier for them) it does not provide as good of reception. I have had Sirius (and XM) in several cars and this setup causes some dropouts in tight narrow spaces (between buildings or under trees).
You can save up to 18 presets, 6 each on Sat 1, Sat 2 and Sat 3. You can go through the presents with both the steering wheel controls and or the touch screen.
Toyota dropped the ball here, it does not include the complete song and artist info. My 2003 Dodge Ram supported this why can Toyota get this right?
They do a great job with Mp3 and WMA cd's
I love having Sirius built in I just wish that they get with it on the interface.
