Convert 2003 Navi / Computer to 2006 or 2007

HI All,

I am contemplating an upgrade to the Navigation / Computer system on my 2003 LC. The 2003 has the updated dash so it should be the same as a 2006 or 2007.

What would I need to get:

a. Bluetooth button on steering wheel
b. 5th or 6th Gen Navigation with Bluetooth (is that where the Bluetooth is integrated?)
c. High-Res Screen

I was hoping to find the parts used from junkyards or ebay.

What do you guys think?

The Gen 4 navigation is on '04-'07 Land Cruisers. My '04 has Bluetooth. Changing an '03 to Gen 4 may require changing the nav computer/dvd under the passenger seat, in addition to the display and controls. The connectors on the wiring may be different too, so it could require a lot of disassembly-reassembly and learning the necessary cuss words.

So all LCs from 2004-2007 use the same Gen 4 Nav?

How difficult is it to swap steering wheels?

Did you ever move forward on this? I'd love to do the same on our '03 LC; Bluetooth and backup.
