Most drivers use Waze, which is the most accurate GPS in terms of traffic, accidents, road works, etc.. But you are free to choose the GPS you prefer!
You have a large choice :
<ul>
<li>If you have an Android, you can use Waze, Google map, TomTom, iCoyote or Mappy GPS.</li>
<li>If you have an iPhone, you can use Waze, Google Map or Apple Map.</li>
</ul>
To modify your GPS :
<ol>
<li>Download the GPS of your choice onto your phone.</li>
<li>In the Heetch app, go to the menu and click on "settings", then "GPS".</li>
<li>Choose the GPS you want among those available on your phone.</li>
</ol>

A new feature is available on Iphone: the automatic opening of the GPS as soon as a journey is accepted.
More convenient, faster and easier, update to iOS 5.36.00 and go to the "GPS Settings" section of your app to activate the option.
