It appears the aux plug in the HK Radio has broken. I use it to hear my GPS and XM Radio on the factory stereo. Is this repairable, or do I need to just start using my Walkman earbuds? I'm good with a soldering iron, so if I can get inside the radio, I can fix it. I use the CB and the Intercom, so going to a different radio won't work. 2011 RGU. Thanks.
