My car is a 2010 with iDrive and a single CD player. I currently listen to music via a USB memory stick however, the quality is very poor and quiet. I expect this is down to using iTunes to copy my CD's so firstly I was wondering if there is a better way to get music onto the memory stick improving the quality. Secondly, is there a better way to play without using the actual CD's, using my iPhone 7 some how for example?
