Note 1: this is a can232 car, and you'll need those libraries for sure.
2: the radio can bus is 83.3kbps (white&orange[H]/white[L]) the canhacker id for that Baud rate is s051C
3: the diag port (via the odb2 is 500kbps, however, you need to send the right code to get through the gateway, which I don't yet know)
4: the arduino bus rate is 115200 and the uno runs at 16mhz

Notes:
00 00 must follow other commands to "ready" the system
in CAN HACKER it looks like:
