is there any way to get factory style bluetooth on 01-03 ls430 like to one on 04-06???? has any try??? By looking at some tech manuel it seem that both gens have the same navi headunit, but i could be wrong...it seem like all they changed was the nav dvd drive in the trunk. So can the bluetooth module be a plug in??

 

I don't think you can upgrade the nav to the BT compatible. As I recall, there is also a control for the BT on the steering wheel for the models newer than ours. I ended up having a Parrot 3200 LS Color installed and am very happy with it so far. I have a 2003 LS 430.
