Thanks to a forum member who posted a video of how to remove the fascia to install a replacement stereo, I replaced my aftermarket JVC CD with a Sony double din DVD player with Tom Tom navigation. All was fine for a few weeks then I drove too fast over a smallish speed bump and my player went off. I've removed it and checked for loose wires, yellow and red power wires and black earth all seem ok. I swapped the fuse at the back of the set with the one from the JVC that I took out I've checked and swapped the 7.5 a fuse in the drivers footwell marked ACC and done the same with the 30 a fuse marked radio in the black fuse box under the bonnet. Is there any other fuses I should check ? Any ideas anyone?
