I installed a Kenwood USB Bluetooth Double DIN radio in my 2007 Ram. I'll post up a few pictures of the modifications. Also, I bought several USB chargers and 12v outlets. I placed them inside the center console and the on the back side for the rear seats. When you have kids, they all have a phone or tablet that needs to be charged up.

I also installed a license plate rearview camera, the monitor is seen in below. I bought an extra camera for the back of my travel trailer when I'm towing.


On the radio, I had to make some brackets on both sides to bolt on the radio up.


I cut down the trim piece below the radio and filed down the upper edge




I bought these dual USB and 12v power outlets from Ebay for $8 for a set.









Here is the underside of the panels

 

I like those dual usb outlets, wonder if they make one that would use a factory plug...

 

They are super easy to wire up. Just normal crimp spade connectors.
