ok im going to buy an in dash dvd/cd/cd r player and want to hook it up to one of those widescreen monitors and mount it in the passenger sunvisor. How are these things hooked up? Is it just a set of a/v cables that run from the monitor to the in dash dvd? Also is it difficult to hook the in dash dvd to my aftermarket cd player/am fm tuner. Any other help would be appreciated, im really new to this.
