Porsche Sat Nav

[secretagent]

Hi I have heard you can change the voices by buying a cd/download on Sat Nav systems to say Ozzie Osbourne or James Bond. HAs anyone done this and it worked? Also has anyone done it on a Porche Cayman 2006 model? I want to buy a new voice (Kit from Knightrider) for my boyfriends car but want to make sure it will work with the Porche sat nav. Any one got any tips? And know what make/model it is?
thanks loads!

Don't know about Porsche Sat Nav, but there are loads of voices for TomTom - Kit, Ozzy, Bond, Austin Powers, R2D2, Joann Lumley etc are examples. OE Sat Nav is on a disc, usually a Blaupunkt product, therefore highly unlikely you could add to it.
