'06 Sonata LX radio changes to 87.7 FM when switching from CD to radio
 

Has anyone else experienced the radio changing to 87.7 FM when
switching from a normal music CD (not MP3) to the radio? The screen
will display preset 5 and a frequency of 87.7 FM, which is just
white-noise up here in cow-hampshire.

I have tried several times to duplicate this, but it only seems that it
happens when the car is first started and the CD is turned on directly
(by pressing "CD" or by normal power button and CD resumes), then
switched over to the radio (via the FM/AM button). And it only happens
with a normal CD, not an MP3 compilation.

Any clues?
