Excuse me for my english,I'm trying to improve it(I live in italy)......but I think I can suggest you about your decision,because I had the same doubt about two months ago before ordering my new ML400CDI....<br> I talked with car audio installers and I also had the choice to hear the audio system(bose).......<br> and after that I decided to take it with is basic audio system(not the bose sound system)!!<br> Than I find another ML(with standard speackers) owner who changed only the MB audio 10(standard)radio with a becker mexico pro radio(that seems done for mercedes cars-infact MB audio products are becker products,but the basics ones!).....<br> And I think that if you are not looking for sound excellence,it could be enaugh.........<br> <br> If you are looking for something better.....I suggest you the becker mexico pro cd(with 3 pre-out +1sub out)as radio-cd,and to install different speackers and obviously good amplifiers..........you will see that you will spend even less than buying a bose sound system!<br> It all depends on the components you will install obviously!<br> <br> Listen to becker mexico pro sound and than you will have no more doubts about it! <p>pi1-820.dialup.tiscalinet.it
