Im interested in this head unit Amazon.com: Boss BV7320 In-Dash 3.2" DVD/MP3/CD Widescreen Receiver with USB (Detachable Front Panel): Car Electronics , Amazon says it fits my 2000 Tj but im not so sure on how accurate that is. Is it as simple as measuring the open space or is that not right? it says the dimensions are 7 x 2.2 x 6.2 inches but at another spot on the page it says 3.75 height and 9.5 width? will this work or is it too big?? any advice is appreciated!
