You only need a k-can cable with an 06 which is cheaper.
I got one off ebay along with a software package that included
the three base programs inpa, ebidas and ncs expert with the addition
of DIS57 SSS and TIS. The whole thing cost 50 bucks shipped.
You need to know your way around PC's to install this and you need
a computer with a 32 bit operating system to make ncsexpert to work
an or a xp emulator program. The base programs were not that uptodate
and I had to update them . Its getting hard to download this stuff or maybe it always was. You should read the big sticky at the top of the page to see
if this is something you can deal with.
I was able to get DIS57 to work but not SSS which is probably just as well.
