Hey guys,
I have a 2003 E500 and want to replace the head unit (It's the half screen, no Bluetooth, etc..). There is a member on here selling a head unit from a 2006 E350 with the full screen. Would this be a straight swap, plug and play if I don't care about installing the Navigation unit in the trunk? Would it still work as a radio and allow me to use Bluetooth without having to rewire everything?

The part number for the unit that I'm looking to buy is: A2118202797

Thanks!
Mike
