The early NTG Audio 20 built between 2015 and 2016 are the same as the newer NTG Audi 20 units that already have CarPlay Android auto-enabled. The only difference is that the software installed in the older units does not have CarPlay and Android Auto enabled. Mercedes-Benz dealers can perform a firmware upgrade and enable CarPlay and Android Auto. This procedure typically takes about one to two hours and requires Star Diagnostic scanner.
