Twice in the past couple of weeks my car radio has spontaneously switched inputs (from USB or Bluetooth) and jumped straight to the Newstalk ZB channel. Now, either my car radio has suddenly developed extreme right-wing tendencies, or someone is doing something odd with the emergency broadcast signal that RDS-capabable radios support in order to enable them to do exactly this.
It's behaved for the past 6 months, maybe some CD post-quake testing?
I don't have this station in the head-unit's memory, and it's a UK-sourced Alpine (as local models didn't have the ISO connector I needed). It's pretty wierd. Any ideas or other folks that have come across this?
