Hi, sorry if this is posted in the wrong place - it's my first post. I can't get the front or rear sensors to work on my 08 IS220d sport. The rear camera works fine and the park assist is switched on (the green light to the right of the rev meter is on), the sound setting is on maximum (set via the nav system) and there's no warning messages coming up to say there's a problem. Any suggestions gratefully received.
