I get occassional TI system messages on the MMC in my Pajero.  TI = traffic information according to the manual.  What other manufacturers call TA or TIM.

The volume is very low but it sounds like persons talking on two-way radio.  I'll see if I can increase the volume.

While this isn't problem, it has me curious.  I don't think we have a TA systems in NZ.  So I'm wondering what the system is picking up?  Some sort of interference?
