I’ve been tossing around the idea of moding the dash for a double din head unit. Used to have one in my TJ and really enjoyed some of the features (especially a backup cam). Most of the pictures I saw involved moving the hvac controls down and deleting the center vent. However, as has been noted, the center vent is attached to the plenum and if I moved the hvac controls there it would not seal the plenum back up. I would also loose the center vent and I actually really like that vent. So instead I decided to move the hvac controls to the top and move the radio to the center. I plan on running a Sony CarPlay headunit like the ax1000 which has a single din frame but a double dine screen. I’ll post pics on how I will install this setup. I plan to retain the center vent as well but move it down about 1/2”. Should be a good clean oem looking mod when done.
