techie,
I know I'm late to the party, but I have a 2008 (12/07 ) LX570 and I want to hack into the nav interface, but not for the reasons most want to. I don't care about watching DVDs while I'm driving, I want to rewrite the audio UI.
Enabling the nav while driving seems to be well discussed, but I haven't seen this yet.
Any interest?
Davy
