Anyone having problems with HD radio reception? The HD radio on my 2013 was working fine up until a couple of months ago when the HD radio stopped working reliably. (Yes- the soft button for HD radio is on). And now it doesn't work at all. I removed the unit and cleaned the antenna contact which seemed to help for about an hour. The it reverted back to no HD reception. Additionally, the FM reception is very noisy now. Any ideas? Perhaps a fouled antenna wire?
