2005 honda odyssey radio controls on the steering wheel, the volume up button changes the station while the volume down button turns up the volume

There is a service bulletin about this. the steering wheel has to be removed along with the switch gear. then the steering shaft ring that makes contact for these controls while the wheel is being turned need to be gently dimpled to make better contact. if the dimples are too extremem the whole steering column will need replaced.

Sounds like the sort of job i relish ,stripping the steering column and reconnecting the wires
