@xanderh,

TomTom is working on with Google to test Android Auto. (But only TomTom Go)

[Only registered and activated users can see links. ]

But there is nothing in the pipeline for working on Head Units.

TomTom NDS works with Toyota as a link to the Head Unit screen.

TomTom NDS is not been tested to work on and Head Units.

Nor will TomTom support Head Units......;


There are a hand full of users who say they have gotten one or the other TomTom GPS apps to work.

So TomTom is not going to answer you in regards to the TomTom NDS app because it is not for the EU market.
It was made for the South American market.

Put it on a smartphone and be happy it work there.
