great, I was going to change the standard lexus head unit for a clarion system with DVD Touch screen but I wanted to keep using a lexus navigator screen so if I get a clarion in one of the DIN's then use a second for a PC hook the PC to the Lexus Navigator screen can keep the GPS on that as well as internet etc, then have a Clarion system for music. Sounds like a plan to me now all I need is alot of money
