@CaddyCTS,

We go through this once a week about Head Units from new users.

It is a smartphone app that can be linked to some Toyota Radios.

Please take the time to read all about the TomTom NDS app.

[Only registered and activated users can see links. ]

I quote them or read for yourself with the link.

"TomTom (TOM2) launched a new navigation app that can be mirrored to Toyota vehicles’ in-dash screens using SmartDeviceLink (SDL) technology – a first for both TomTom and Toyota. The TomTom Navigation App is available at no extra cost to Toyota drivers in Argentina, Brazil and Paraguay – on both iOS and Android™ phones."
