Xovision 7" In-Dash Double Din DVD

anyone has any tips about this head unit for my 02 mustang...i need to replace my factory one and would like to find something nice and not that expensive...i saw this one at walmart and though its double din i don't know if it will fit ...i understand i will need an amp integrator and a kit. but i don't want to go thru all the trouble with harnesses if it doesn't fit...help
