TomTom Digital Cockpit comes with a stock application for an in-vehicle communication experience. This communication experience is comprised of two parts - phone calls and messaging. Users can access their entire contact list and call history by using the communication app. They can also make and receive calls from their synced phone book via connected mobile phones. Users can also receive messages through notifications which they can read aloud, call back, and reply to with preset messages.


The Recents tab displays phone call history synced from a connected mobile phone. Calls are categorized into three groups:

  • Today: Calls from the current day.
  • Yesterday: Calls from the previous day.
  • Older: Calls from before yesterday.

The recents list is arranged in chronological order, with the most recent calls at the top of the list. If there are no recent calls for a group, then the group will not be visible in the list.



The Contacts tab displays the phone book synchronized from a connected phone. It has two parts:

  • Favorite contacts
  • All contacts

Favorite contacts

The favorite contacts list is a duplicate of what is on the user's mobile phone(s), synchronized with the TomTom Digital Cockpit. Editing or adding favorites in TomTom Digital Cockpit is not supported. If the phone holds no favorite contacts, then the favorites section, including the "star icon" header, is not displayed.

All contacts

All contacts, including favorite contacts, are displayed in the "All contacts" part of the screen. By default, contacts are sorted alphabetically on the first name, and grouped on their first letter. Contact names starting with non-alphabetic characters are listed in the "#" section.

The sticky header fixes the alphabet header to the top of the contact list before, during, and after a user scrolls down the list. When a user scrolls the list, the slider on the right side of the panel moves vertically, indicating the scroll position.

Scroll bar

The scrollbar indicates how far down the user is in the contacts list if the content is taller than the viewable area. The scrollbar lets the user navigate to the rest of the contacts by moving the window viewing area up or down. Tapping anywhere on the scrollbar will move the content by increments equivalent to the height of the screen, with a pop-up alphabet indicator.

When the user taps on the search icon, the Contact search opens in a new view with a keyboard (only when Safety Lock is off). The searches will be automatically completed when a user starts typing.

The content of Contact search starts with a list of All contacts below the search text field. Users can tap on the Back button anytime to cancel the search and leave the Contact search view.

Initiating or accepting a call

When a user initiates or accepts a call, the call is handled by a Main Process Panel which is displayed on the Home Panel. This ensures that essential call management functions are accessible to the user at all times.

Customizing communication

Only some components in the communication app are customizable or swappable. If a highly customized component is needed, replacing the entire communication application frontend is the best option. However, it will be faster to use the stock communication application and customize it to your needs.

Quick-reply options1) Default quick replies: Incoming call notifications have one quick-reply by default, which can be translated into different languages or changed. The user can enable or disable it. 2) Custom quick replies (defined by the user): The user can choose to have no quick replies or add their own quick replies. However, this will require a custom frontend and more development effort.
