Default Re: OEM radio
Anyone buying a used OEM radio would be wise not to buy one with the part number A 193 820 00 86. The 00 means it was the first version radio and they had problems with display being hard to read in daylight. There probably are a few out there, though most will have been changed under warranty. They were fitted to the 2004 models only.

So buy the A 193 820 04 86 models they are the fourth upgrade.
