If you saw the Mk.2 production line you would know it's FAR from home brew. (Actually I think you can see some of it at the geek site).

For all intents and purposes there was a single Mk.2 production run and then a single Mk.2A run. Production glitches ALWAYS show up in the first production run (known as ramp up) and are fixed as the line progresses - but in the case of the car player there was no more production to follow!

The glitches can be counted on one hand, have been well documented here, and are fixed at no cost to the owner. In all cases (that I can think of) they are supplier screw ups not design flaws, despite the suppliers that were used being HUGE in their respective industries. The only very widespread issue is hard disk cables (the supplier was changed without our knowledge or approval and the part was not verified). The docking connector issue was widespread for Mk.2 but fixed by Mk.2A.
