hi, i have just installed a new touchscreen stereo into my grande, all was good, and all speakers where working, i removed the sat nav unit from under drivers seat yesterday, and now the drivers front speaker doesnt work, im assuming it might use that speaker for the voice guidance and know i have removed that from the system it doesnt work? has anyone had anything similar?
