My car's audio is normal now,I want to upgrade to ENTERTAINMENT PACKAGE(harman/kardon logic7 audio).I have asked MB dealership but they said that they would not do that.I would like to know if the vehicle has any reserved lines to install the equipment，are the fuses and wires available for new equipment?
Please share your opinion,thanks

@ktar I feel you, I have 2016 GLE350 with HK system. HK is a great system but nowhere near Mark Levinson...
