Blaupunkt Brisbane SD48.
$159.99 from Crutchfield, which included a full fitting kit and shipping.
Features up front SD card reader and Aux input, rear mounted USB with included cable (which I've run into the glove box).
Rounded edges and curved front panel work really nicely with the Focus aesthetics.
Sounds great, even with the stock speakers. Much better than the factory deck.
Included American International fitting kit feels nice and solid.
