The other week on the run out to Bathurst I caught myself out hitting a really rough dip a bit quick with the CD player going. The player stopped immediately and gave me a "FOCUS Err" message on the display. Turning the Mac off and back on again had no success (was still driving at this stage). Changing discs seemed to get the player working again (had no trouble with am/fm).
I hadn't had any recurrence in the past two weeks until this morning on a road with some relatively small surface joins. Changing discs and back again seemed to clear the fault
I presume this error is trying to tell me the laser has copped a jolt. Can it be fixed? Is it going to be exxy to fix? Should I just let it go until it dies altogether and replace the HU and AV panel?
