hi every one
i know its a bit cheecky but all the help would be greatful
i have an e39 m5 2000 and i retorfited the tv mk3 satnav
basicly everything works baring the sat nav
a friend of mine gavce me his map cd and the map works
i get gprs signal but if was was it just say put my work adress in and im at home the satnav would pick up were i am but wont do anything else it wont guide me to my destination it wont tell me when im there it just shows were i was
now because i fitted this set up i dont know if it need to be updated or if i need to get it upgraded
after reading a few post theres differnt versions updates would it be a simple job of updateing me satnav driver?

thank you
