"For those of you with HD Radios, for the last week or so, when the HD
signal kicks in, the output is very choppy. This is true for all
stations, AM or FM. Attached is an mp3 file which explains."

"this same problem just started today for me as well, anyone has any
thoughts what is happening? regular radio works fine, its just when i
switch on HD, it gets all choppy"

"Dealer could not fix. Submitted a PUMA case."
