Hello.i have bought a car recently, everything seemd to work fine, until it appeard on the screen suddenly "please insert update cd". I was at Citroen and they put a cd inside but the update could not be made and the cd remained inside. I searched a little bit on the Internet and I found how to hard reset myself and I succeeded. On the screen appears new logo, but there is no sound. No parking sound, no radio sound, nothing. I was at Citroen again, as I looked on this topic and I thought it will solve with lexia but they could not seem to make it work. How you solved your problem?! I desperate need some help
