Query: Works OK but mechanical noises were too much to overcome

Bought this to play tunes from my iPhone 3G in my car. Works as advertised and sound quality was OK, but the unit rattles and crackles in the tape player so much and so loudly that I just couldn't stand it. Very distracting - completely overshadowed the otherwise acceptable performance of the unit.I'm taking this thing back and looking for a more solidly built unit to do the job.
