Aftermarket command
I just bought a 2008 ML550 in very good condition. However, the command center is totally outdated - every little thing needs an adapter from blue tooth to IPOD.
What I want to do is to replace the command center with one that has GPS HD navigation, WIFI, bluetooth, IPOD adpter etc. and keep my 11 Harmon Kardon speakers intact.
It looks like the 11 speaker Harmon Kardon speaker harness will be the major stumbling block. Is that correct? If it is correct then can I get an adapter for the Harmon Kardon speaker harness which I can plug in to the after market system and play it through the existing Harmon Kardon speakers. Can somebody help me please?
Thanks
