When it comes to video/navigation head units, there are so many more options with a double-DIN than there are with flip-outs. With better fit and finish, not to mention better controls, and a cheaper price, double-DIN is where it’s at, but what if your car does not have the option for a double-DIN head unit? If you have an adventurous spirit, and are willing put the blade to the dash, make it fit! Recently, I had a late ‘90s Chevy Tahoe in the shop to get a new video screen. The owner had a larger-face single-DIN DVD head unit that was giving him fits, so we upgraded to a new Pioneer AVIC double-DIN DVD head unit.
