04 Nav/Stereo Trouble
 

So my 04 HSE7 has the Nav deck in the dash with the cd changer under the pass seat. I can play single cd's in the dash but can't make the changer work.
When you load the changer it goes thru the motions checking for cd's so it is powered up but does not play.
I swapped it out with a changer from my 2000 parts truck but had the same results.
Called the local stereo guys but they said there isn't a replacement deck listed for my disco.
Any help would be appreciated. Thanks.

Try pulling the fuse to the Head Unit for a full reset. They can be kind of flaky at times and generally a full power down will solve the issue. Sometimes a soft reboot will work as well. To reboot, press the "tp" button + the 3 & 5 (third and fifth bottom buttons).

Will try the fuse when my wife gets home. Thanks Tee

Now I need a security code for the radio. Any ideas?

Got the code from the dealer and have the radio working again but still can't make the changer work.

When the changer is going through the motions and loading the CD's is there anything showing on the head unit screen in the dash?

Its highly unlikely that the head unit is the problem unless there is a communication problem between the changer and head unit. Its hard to diagnose without knowing if the changer previously worked fine and this is a recent happening. As for swapping the changer from the parts truck, that has me a little stumped too, but I still think it has nothing to do with the head unit...the only way to be for sure is to try the original changer in the parts truck....if the original changer works in the parts truck then its the head unit.

You can get used replacement Nav head units on ebay I would imagine..

The changers go bad all the time. You probably just have two bad ones. Of all of the discos I see, we usually have to junk over half of the changers.

When the unit is in the single CD mode does "CDC" show in the bottom right of the screen.

Also is this a new to you disco that arrived with this problem, or something that just started?

No it doesn't say anything on the dash deck when it's loading the changer.
Ya know, I never tried it in the parts truck, just took it out. I'll plug it back in and try it.
