my ES-300 has been diagnosed as having an amp that fails intermittently causing the battery to drain overnight. my LX dealer says that the solution is to replace the amp, with its attendant high cost. I'm considering having the system replaced completely by a plain-vanilla stereo. the mark levinson system came with the car (I got it used) and its way more than I need. anyone ever just replace the whole kit and caboodle. I realize that I'd lose the nav but given the capabilities available on smart phones, that doesn't seem to be a great loss.
any thoughts?
