CD Changer/DICE -- Amplifier Problem???

[joegoodrich]

On my 2000 X5 4.4... I recently began to have audio problems with the CD changer. The left channel would sound very distorted like a blown speaker after about 5 minutes of listening. Sounds fine in the first few minutes.

The tape player and AM/FM tuner sound fine.

I decided to take out the changer and I installed the DICE controller for my iPod.

Now I have no audio out of the left speakers when running the DICE. The tape and AM/FM still are fine.

Where should I check next? I thought maybe cable is bad or the amp is going bad - but I'm confused because it only affects the CD changer input.

By the way this is with Navigation and NO DSP.

Any help would be greatly appreciated!!!!

Sounds like you have a bad channel in the DICE module. Where was the kit purchased from?

You will need to contact BSW to arrange for a return since they are your original seller.

Followup:

I reinstalled the CD changer to eliminate DICE problems. The CD audio is fine until after about 5 to 15 minutes then the left channel gets very distorted.

I figured it might be an amplifier problem so I replaced the amp. Same problem exists.

So now I suspect the head unit. Am I on the right track? Would the head unit cause left channel audio problems out of the CD changer input only. The AM/FM and tape work fine.

If you switch the fader left to right does it crackle? Or go in and out?

The right channel (Front and Back) always sounds good. The left channel (Front and Back) starts out good and goes to crap after about 5-15 minutes but only on the CD Changer input. If it goes bad and I switch to tape or AM/FM, and both left and right sound fine for those inputs.

Okay, I am getting ready to replace my radio module. My X5 is a 00 and has a BM C43 with round pins.

I'm going to replace it with the BM53 that has flat pins and is coded for my nav.

I have included 2 pics -- 1 old and 1 of the new unit. What do I need for adapaters to convert round to flat?

On the old unit there are two plugs that look like antenna plugs separate from the main harness. Which is which. I assume one is for the radio antenna and one is for the nav antenna.

Simply need our PlugPak:

BMW Radio Tuner "PlugPak"

This will include the necessary adapters to install your new radio.

If you have NAV, then you would need to take a look at the Board Monitor Radio (BM53) which is located in the trunk. The CD Changer directly connects to the BM53, so perhaps the radio has some how failed for that particular input. Its odd you get a similar problem between changer and DICE. You've already replaced the amplifier, so the BM53 radio is pretty much the only thing left to replace.
