I'm looking to upgrade my Shaker 500 head unit with an aftermarket nav system. There are a number of good systems with 7-inch screens that will drop right in, but I would really like to install the Alpine INE-Z928HD head unit, which is double-din sized and comes with an 8-inch screen. Alpine makes a bezel that permits installation in a 2010+ Mustang, but nothing has been released for the '07 - '09 cars. Has anybody tried this or know someone who has? Many thanks for any leads.
