As do I.
As far as LCD mounting is concerned, it seems like the in-dash option is certainly the best. If you wanted to squeeze the HVAC controls down (and make a new bezel) you might fit a 7" in. If you relocate the HVAC controls to the center console (I've seen it once) you could get a nice sized LCD in there.
A roof mounted one blocks the rearview mirror... The shifter takes up a lot of the center divider space. I don't want sunvisor LCDs... I think I do want a H/U setup...
I'm in a tough situation.
