I have an after market kenwood headunit fitted . justed modded the cd changer connector ( pins 9 and 1 linked and pins 8 12 and 6 for audio in ) for aux in. now have the head unit in the glove box .
i have climate control so no aircon dials for me to deal with.
i would make sure that a 8" lilliput will fit first. should be some measurements on the http://www.digitalww.com web site. the 7" just fitted in width .
