Hello I have a Mercedes SLK R 171 model 2009 with a unfortunately used Comand NTG 2.5. Despite intensive efforts I could not find a replacement for the scratched front panel, on which the buttons also replace the paint, so that I now want to change the radio. Does anyone already have experiences, or which reasonable equivalent radio is desirable. Can I keep the steering wheel remote control? Thank you for your information, warm greetings from Austria
