I saw Metrik 6-inch TFT Sunvisor Monitors on overstock.com site for $179.00. Anyone know if this brand is any good? They look nice. With the limited space in a 4th gen, it would work out well.

they have all kinds of good deals there. Not sure about the monitor, though, sorry.

 

I bought something like that for my car.. They are great.. Great picture quality.. BUT they are far from universal.. I had the toughest time getting them in my car.. They had to be painted to match my interior and forget about using the factory clips.. You are going to have to fabricate your own.. It is worth it if you have the time to get them fitted just right.. But you might be better off just getting visor monitors and mounting them into the OEM visors yourself..
