The matching Audi OEM 6-disc CD changer (part # 4B0 035 111) is made by Matsushita and, of course, is plug-compatible without any modifications. The correct CD magazine for this changer is part # 3B0 051 179. The Concert radio can also be used with some aftermarket Panasonic CD changer models with an appropriate adapter and installation kit. For example, the Panasonic DP601, DP610, DP801 or DP810 changers are compatible. Look for them at Autotoys, Aamp of America, or your local car stereo specialist. There is also a 6-disc CD changer made by USA Spec that is also compatible, available from Crutchfields and other specialty car audio dealers.
The car comes pre-wired for a CD changer. The stock mounting location is in the trunk, in a plastic box (which is supplied with the installation kit) located to the left on the trunk floor.
This radio is compatible with the Audi PhatNoise digital audio player, see below.
