Does anyone know whch overhead DVD monitor would work good with the AVIC-Z1? I am looking to put an overhead DVD Player where the dome light (replace the light) is on my 2007 Avalanche and don't know which would be a good choice. Thanks

Any one will work with the Z1, so basically you just need to decide which features you want. Things to consider are size (obviously), built-in DVD playback, wireless transmitter for headphones, etc. Once you know which things are important start looking at the major brands. Any high quality panel will give you good picture quality.
