We recently got an is200 sport for another run around car, its so far impressed me with the features and the handling that i find better than the 3 series, but 2 weeks down the line the cd player is busted. Now i know this is common for the IS, which means there must be a sensible easy fix for it as far as replacements go? i realise i cant just plug an old headunit in because my model has an amp. so im just wondering what my options are here without shelling out a fortune.
