Hi. Pull the
ICC out and see if any of the terminals in the plug on the dash have been pushed out of the back of the plug by a bent pin on the first faulty
ICC. Main pins to check are the B+ on the bottom edge far right and the acc and ign feeds on the top row near the centre of the centre section of the plug and the ground wire above the B+ power wire on the right hand edge. The main thing I would be looking at is the B+ feed as radio should work in key-less mode without acc or ign and it should earth through the side brackets upper bolts and the antenna module if the earth pin is gone. If all the terminals are in place the next thing is to see if there is power on the B+ terminal. Good luck. MD
