Hi TerminatorX5, i guess it must be all custom when i looked at the website i was not sure what to buy so i contact them and a guy called jon replied saying if i have a pressed dvd then i would need to buy the firmware and maps or if i had a relatively new disc with speed cams etc i could get away with just purchasing the firmware for £5.99 to be honest for the extra £7 i thought i would just buy both kr chris
