check engine light JEEP GRAND CHEROKEE 2021 Owner handbook (in English)

• If you are using the built-in Uconnect navi-
gation system, and you try and start a new
route using CarPlay, via voice or any other
method, a pop-up appears asking if you
would like to switch from Uconnect naviga-
tion to iPhone navigation. A pop-up also
appears, asking if you’d like to switch, if
CarPlay navigation is currently in use and
you attempt to launch a built-in Uconnect
route. Selecting “Yes” switches the naviga-
tion type to the newly used method of
navigation and a route will be planned for
the new destination. If “No” is selected the
navigation type remains unchanged.Apps

Play, you must have the compatible app al-
