Was that with the magnetic sheeting??

I had this problem with my first DICE along with what sounded like tape hiss. Dension sent me a new unit and it was clear as a bell. Now the whining sound is coming back.

Tom - what is happening for the unit to sound so good on initial install and then slowly start getting worse?? The unit is in the exact same place as the last one and no changes have been made to the system.

No sheeting yet. I just ordered the sheeting yesterday. I wanted to add the sheeting to provide more protection against interference.

Where is your DICE located??

As long as nothing has changed in your configuration - it shouldn't change in the DICE. Try relocating your module to a different area of the vehicle to see if this changes things.

It was installed just what the instructions asked for on the X5. It was near the ashtray (I also bought the ashtray Ipod dock) standing up sideways on the driver side behind the side panel. Now, it's laid flat in the same area and I also rearranged the wires in the back where the multiple disk player is located. So far it's been working for two days.

OK, I have mine sitting under my driver's seat. I will have to try a new location.

Let us know about the magnetic shielding - I have another project I might want to use that on.

Update after all these years:

It turned out that the magnetic shielding did not work at all. I finally found a solution shortly after this post. I just strapped down the DICE box module with a several plastic ties near the connection area really tight and left the module in the same place. The whining noise never came back since. The hiss noise is to a very, very minimum. If this works, make sure the module is stabilized in a good area with no movements.

Excellent thread as I stopped using the Dice (Aux) hooked up to my sons Portable DVD player as the whine noise when he was watching movies became unbearable.
