On my business cd. I can't change radio channel.volume works OK but won't change channel.buttons are not responding.
Anyone any ideas?
 
This is only a guess. When my battery was on its way out my iPod wouldn't play through the Aux in.
These cars are very sensitive when the battery is on its way out.
What's the condition and age of yours.

That was just it Bandit. Mine was showing no problems with the battery, it started with the IPod only playing for about 20 mins then only a couple of tracks then nothing.
I was all ready to strip out the radio thinking the aux cable was knackered.
Then realised my battery charger ( mines kept on a trickle charger) was not showing fully charged, I'd had the car 3:5 years did not know the history of the battery.
I changed the battery and everything worked again as normal.

I'm only suggesting it may be as these cars are very sensitive to poor battery condition.
Some show dash lights some show Windows not working others central locking it can show in all different ways.
It maybe a good starting point to check battery condition before you start ripping out the radio :thumbsup:
 
Open to all suggestions.cd plays,the one radio channel plays although the buttons won't change cd track or radio channel.
I would have thought that while driving even with a suspect battery that there should be enough supply to run a radio.
 
My radio preset buttons 1 and 3 don't work either. Press them and nothing. I put it down to having an old radio with two dodgy buttons. My CD changer doesn't either. Loads, buzzes, then tells me no disc.

So I have put in an aux lead and use an MP3 player.
