I'm guessing you didn't have your radio switched on when you did the test? The IIC (or I2C - I 'squared' C) is a component interconnect bus developed by Philips. In this case it is the way that the Sat Nav communicates with the Radio for things like the display of the radio channel, volume, etc.
Try the test again with the radio switched on.
By the way, if you suspect problems with your TMC there is a diagnostics screen that shows signal level and quality.
A RED indicator show that you have a TMC disk but that there is no signal (from Classic FM)
Disagree about the bit about red indicator. Renualt didn't sign up to an agreement for the TMC service until August 2004
My 2004 Laguna came with a 2003 disk and the TMC option was red up to I upgraded the disk. Didn't realise Clasic FM was the data provider thanks for that bit of info.
