I have a 2004 Grand Voyager 2.5 CRD which I fitted a new battery to a few weeks ago. Since then the CD autochanger won't eject any CD's and alternates flashing of the 6 LED's on the front of the unit. Left 3 then the right 3. This sequences continously all the time I'm driving. I tried disconnecting the battery for 15 minutes, 60 minutes and 120 minutes but this didn't help. The radio works fine, in fact the radio doesn't even ask for my pin code when I power it back up. If I could enter my pin code it may reset the CD changer.

 

That thing is a boat anchor now. Get yourself a new one a Crutchfield or somewhere.

 

But I don't have a boat and I'd rather spend my money solving my ABS warning light issues :-)
