Hi

I need help please.

I have E220 CDI Kombi W211 of 2003 year and have install a headunit audio 50 APS cd navigation i have too the sound-system harmon/kardon LOGIC7 surround.

My question is:

If i upgrade the 50 APS for a comand this headunit is compatible with harmon/kardon LOGIC7 ? or not?

please help me because i will buy an headunit dvd comand + dvd drive navigation but i like very much the sound of harmon/kardon LOGIC7 and I do not want to be without it.
