06 RX400h gen 4 nav upgrade to gen 5
I would like to upgrade my 06 RX400h nav from gen 4 to gen 5. I have seen posting of someone possibly offering an upgrade from $2500 for the nav+ecu - $1000 after sending the old system in. The upgrade involves a new wiring harness. I have PM the main poster but have not got anything back. I have someone offering me a cheap 08 RX350 gen 5 nav+ecu 
but am not sure of the wiring. A harness would be great or even if someone has knowledge of the wiring that needs to be done would be good.
How about the wiring diagrams of the nav+ecu for the 06 RX400h and 08 RX350? Anything would be appreciated. Thanks

I contacted a guy at Lexus Owners Club and he is looking into getting the parts for me but he stated the hybrid information should not display. Not happy with that. Can anyone validate that since he said "should"? Thanks
