Hi all,
I am a new member but have been hovering in the backround for many years! my 2004 RX330 just got totaled a little over a month ago and just got into an 03 LX470 and I love it! this thing blows the RX away! Anyways, just wanted to let anyone else know that this thing does work WITHOUT the module! Very easy and it took me about 30 minutes to do. I actually did it on my lunch break! It does look very intimidating, but if you follow these directions to the very last detail, it shouldnt be no problem! Now, if anyone out there knows or has done the bypass for the Nav that allows you to input addresses while your moving, that would take out most if not all the cons of the LX470's navigation/ dvd! Anyone know if this has been done? The button taps on the volume screen dont seem to work on the 03's.
