View Full Version : Car Media Docking System CMD310/05 Noise

07-25-2012, 09:20 PM
Hi - I fitted a CMD310 into my Porsche Boxster this evening.

Since doing so, I have interference - a whining noise which the pitch increases with engine speed.

This is strange because the Becker unit which I removed never exhibited any interference at all! Also the Becker unit had no ferrite rings or supressors fitted to the wiring, just like the Philips unit.

What can I do to try and eliminate this unwanted noise? Is the unit faulty? :confused:

Would really appreciate an answer from a Philips technician.

Dear Teknow,

Welcome to the Support Forum!

I'm afraid in this Forum we don't have any specialist / technitian that knows about car audio systems. I would advice you to contact our UK callcentre or your retailer.
