First, the screen is a DV Media M3 Pop-up screen for Mazda 3. It fits 2004 - 2007 (2008 models haven't hit the showroom yet so no word on the 2008). Here is a link to a site that sells them: http://thexenonstore.com/mazda3_screen_info.php
I purchased my screen from a local importer here in Tampa (who also happens to sell them on eBay, click here to check out their eBay items)
. This screen is the definition of plug-and-play in terms of ease of installation. Taking just two screws off the factory dasy and swapping vents this screen was nearly ready to go. What about the wiring
? That was even easier. It comes with a harness that takes your factory radio
plug and creates a pass through cable so the factory plug powers both the radio and the screen. Once I saw how easy it was to install I skipped the car-audio shop.
