Headrests :)
Orginaly I'd planned to fit a freeview box to the kenwood, but to be honest it seemed a bit like overkill. I'd love to fit an xbox (modded) into the boot somehow without getting rid of the spare, I've got a couple of chipped xbox's knocking around that could do with a home! But I'm not 100% sure what I'd do with them. Could either run a video input to the kenwood (and therefore use XBMC from the xbox) or treat the xbox like a USB hard drive as another media source (on top of the ipod)
EDIT: HID's are also on the list, but I know absolutely nothing about them, how to fit, whats good, price etc etc, so it's probably going to the back of the list
nice stereo install i have a Kenwood DDX6029 i took out of my pajero when i sold it, i am considering fitting it in the lex but the standard stereo works fine and i am happy with quality etc
