Hello Forum, I would like to change radio in my Mercedes SLK 230 Compressor 2001 The radio.http://www.mediamarkt.de/…/…-CDE136BT,48353,460793,297549.html?… Will this improve the quality, I find the standard speakers are very modest. That’s why I would like to have better sound. Would the above linked radio fit or not? And if I installed the radio I would have to change something?
