Removed & cleaned the satnav cd drive, tried a backup copy I got off ebay, but say`s `disk unreadable`
So, next I will try a genuine disk from ebay. What CD`s will work on this system? (it`s a Siemen drive unit). I understand they have to be Navtech &/or Peugeot, or will others work?
If I get a recent disk,say 2005-2006 will it work, or must I upgrade the software(how?)
Could anyone load a pic of a working satnav screen(still waiting for my handbook from the dealer...couldn`t get one anywhere else)

Regards, Steve
