I recently bought a used Citroen C5 Tourer. You helped me a lot with updating firmware and maps, so you might have the answer for gthis lame although rather annoying problem of mine. I can't delete archived addresses of the previous owner from the navigation system's directory. It doesn't seem like a big thing to ask from a software but I couldn't figure out how to do it. When I go into the directory I can only select the previously archived address as my destination, there is no other option (therefore can't delete it).
Thank you for your help!
