Two days ago, I purchased a new to me L322. Its a 2012 SC, well taken care of, records, 62k miles. Its a bit of an adjustment from my old P38 but mostly in a good way. I have the HK Logic7 stereo with in dash 6 disc changer, apparently by Clarion. I'm getting an "invalid disc" error that was intermittent at first but now seeming permanent. I searched and see its not an unusual problem just don't see any fixes. I'm not sure I want to rip it apart and devote time to attempting to repair a changer that is aging out and doesn't sound great when it does work. I'm thinking a better route might be to upgrade to a newer model that fits the slot and has compatible hookups. Has anyone found a suitable replacement? Even though I'm little disappointed in the sound of the L322 stereo, I want to keep a factory look and feel. So far, turning off the Logic 7 processing has improved things a little, hoping a new CD will do more. Thanks!
