Okay, I'll be honest here. I'm a little embarrassed. I bought a 5.6" LCD that included a swivel mount that had really sticky two sided tape on it. I removed the rubber mat and stuck it there(directly right on the dash plastic). The next day, I guess the sun heated up the top the dashboard up and as I accelerated, the whole display fell off and dropped right on the gear shift lever and the whole lcd got cracked and totalled. That's why I was asking about the sun visor LCD unit.
It cost me $70 on eBay. Oh well. Maybe I should have screwed it down. It actually was a good spot to put it because I could see what was on without turning my head too much. It's kind of where the Factory NAV would be but a few inches higher.
