After some reserach, i am found solutions from:

nav-tv.com

tvandnav2go.com

tvonnav.com

I am looking to pull the trigger on the 'plug & play' solution & have it installed by my lexus dealer.

Before pulling the trigger, I would like to hear from people who have dealt with any of these 3 companies & what experience they had with their solution in the long run.

Thanks

PS I have a 2006 GS430
