Hopefully they did the update to the trani. i'm sure its done.
There are tonnes of videos, for downloading and installing both INPA and ISTA/D.

Just google it. you will need at least 200 gigs of space or maybe more, it has all the vehicles, wiring diagrams, diagnostics, etc.

i use ISTA/D plus the D+KAN cable you can get from everywhere to connect to Exx bodies, and Ethernet cable i built for Fxx bodies. Coding and programming i use the official ICOM unit . if you are not sure what you are doing it maybe easier to find an indy shop who can do it. its not hard but it helps to have someone teach you, or watch lots of youtube vids.
