I have a 09 plate Galaxy Ghia, with a Ford built in Sat Nav unit (don't know the model, got the owners manual here but nowhere does it give a model number on it) unit has a CD player, SD card slot with card in it, is a blue tooth unit for my phone and Sat Nav unit with a 6 CD Changer attached. The radio is working, but nothing else, blue screen on the unit, no volume control, phone blue tooth not being detected - zilch. Worked fine until this morning when my daughter turned the unit back on to listen to the radio after I'd stopped car and removed key, turned unit off on the volume button when we left the car - so it didn't run for an hour to itself - since then blue screen. Need the sat nav as I rely on it on a daily basis for work, worse than that need blue tooth to phone..... Any ideas. Thanks folks
