Installing my 2004 Toyota Sienna’s Navigation System
I bought my 2004 Toyota Sienna as an almost fully loaded XLE Limited edition. The main thing that was missing was an in-dash navigation system. Since I really value having an in-dash navigation system as opposed to a portable navigation unit (which is more prone to theft), I decided to retrofit a stock Toyota navigation unit into my Toyota Sienna
Typically, you can install an E7001 from a Toyota Solara into a Toyota Sienna. However, I found an E7006 from a Toyota Tundra on eBay, and I was wondering whether it would work as well.
After some research on www.siennaclub.org, I learned that the E7006 is the same unit used on a 2005 Sienna with a JBL digital amplifier.
I went ahead and bought the E7006 taken from a 2005 Tundra on eBay. The part number is 86120-0C160 / DW468100 – 0170. Although the part number of this E7006 is different from an E7006 used in the Solara, I was able to install it and everything worked fine except for the voice navigation.
Here are some pictures:

The rear connectors look identical as the ones on the Solara Nav Unit. I have connected the VSS signal and the brake signal into E5 pin 17 and E8 pin 17 respectively (on the Engine Control Module).
