Hi, I tried  embed a USB modulator on the radio for bmv e46, I'm connected to the TEA 0676, but I have a low level of interference, how to get rid of it
the connection is the following in the picture...

If stuck in the repair and you ask questions, please do it as follows: - Details: Give the exact model number of your device and the chassis ID (if there is). - If possible, please attach pictures of the appliance. - Anamnesis: Write down the exact symptom. If hard to describe the symptom, it is difficult to verbally defined clearly, attach pictures or sound of the phenomenon! - Tell what was you have done so far: search contact error, which parts has examined or changed yet, etc... The incorrectly named topic suspended and will be deleted after 48 hours! Suspended state while others are not able to comment until you correct the address. Subsequent repair of the defective title (within 48 hours) by clicking on the "Edit" tab can be carried out.
