Any luck with this? I'm in need of an upgrade. I too have read the long long long threads but most of the info isnt for the 06 lx and tbh, im not wild about those tesla style screens...I've read through them, the different models have different requirements, the '06 lx470 is mentioned by Ell, but there isn't as much detail for the change as some other models. That's why I'm posting here, under "06/07 LX470 Nav/Radio upgrades"
