The multichanger on my 1998 Elite sometimes fails to operate when I select it on the head unit. Instead it displays 'NO CASSETTE'. To get rid of the fault I have to turn the head unit on and off a couple of times. Any idea's folks ??

What model of changer is it?

Sounds like the damp may be getting at the switches or sensor board failure. Suggest to remove it, place it in a warm airing cupboard for a day or so, refit and see if it works - if it does, brilliant, and if not let me have a model and I can advise further.

Thanks Dave , sounds quite plausable as it normally plays up early in the morning after the car has been sitting on the drive all night. I will whip the changer out in the morning and do as you say.

Pound to a pinch of brown stuff its a ccr600 or ccr800.  This is a known issue on them. A newer software supposedly fixes it, but in my experience, only reduces the frequency of it happening

No, its not a software fix for this fault.

Its a problem with condensation getting into the switches or sensors and stopping them from working correctly and the unit simply cannot detect that a cartridge has been inserted - hence the message "No Cassette"

fairly complex to put right, but not impossible.

The later software does improve it . Turning radio (only) off and on allows it to see the CDC again.  The "NO CASS" message is due to the CDC not being there (as far as the HU is concerned, so attempts to switch to cassette player, which unless there is a cassette in there, will produce NO CASS).  IF a tape is present, that starts playing.

Thus, from my experience (my old ccr600 used to suffer this all the time), I reckon the issue lays in the HU


I do have a theory about tired car batteries being partially at fault, in the same way that Traffic Master often pipes up if battery is down a bit...

I can rule out the head unit 100% as we don`t use head units here to fix and test them !!

What you are seeing though is when the head unit initially talks to the changer, only then will the cartridge detection switches and sensors become active and determine whether the changer can be played. If it determines that a cartridge is not loaded, then it will come up with the error of NO MAGAZINE and it will the revert to playing tapes. This is very different to the error of NO CDC which can indeed be a cause of head unit and software failure where the changer itself cannot be seen.

The error msg quoted was NO CASSETTE (or NO CASS I suspect), not MAGAZINE (meaning no CD Mag loaded on these units).  The CCRx00 don't give a NO CDC error, if its not happy with the CDC, it just ignores it.

The Source selection button - 0 - flicks between sources, in this sequence - Tuner > CDC > Tape > Tuner etc.

In the case of this error, in my experience, the HU doesn't realise it has a CDC attached, thus 0 button goes Tuner > Tape > Tuner etc. So pressing 0 in this scenario, it tries to play tape (which it will if tape is in there, else give NO CASS).


Turning HU off and on, allows HU to see the CDC again, thus back to Tuner > CDC > Tape > Tuner etc


Does that make sense?

I should add this is not a permenent fault like the No CDC error on ccr2006 etc, this is *ALWAYS* resolved simply by switching off and on the ccr600/800

Yep, my error

NO CASSETTE is the same error as NO MAGAZINE

Depends on software version as to the message it gives. Both mean the same though - can see the changer, but cannot sense that the CD cartridge/Magazine is present.

And yes, some versions of CCRXXX will respond exactly as you state.
