i know the Stilo uses 6 bits data packets to send the RDS data info to the display with a fixed tranfer rate - so for example with 12 bytes (96 bits) you can display 16 symbols (16x6=96) on the display. I guess the same trick is used in other Fiat models..... So basically we need a clever guy capable of transferring retrieved OBD2 data to 6 bits RDS data (simple explanation but i'm sure it's not as simple as it seems to be...)
