My friend is putting a system in his Mustang - I've given him a few things to go by, but I've never been big into double DINs, so I figured I'd consult you guys.
He's gonna need something that has at least 2 sets of 4v preouts.
He wants AUX/USB connectivity.
He'd like to have built-in navi.
These are basically three of the guidelines he's going by. Can you guys point us towards a decent touchscreen double DIN that has at least these three features, but preferably stay under $700?
