Possible Cause and Resolution
Symptom
I cannot see SYNC when I
search for Wi-Fi networks on
my cell phone or other
device. –
System limitation.
•SYNC does not provide a Wi-Fi hotspot at this time.
– Weak network signal
•Move your vehicle closer to the Wi-Fi hotspot or to
a place where the network signal is not obstructed.

connection.
•Use a more reliable Wi-Fi hotspot.
Software downloads take
too long.

– Wi-Fi network requires a subscription or acceptance
of terms and conditions.
•Test the connection using another device. If the
network requires a subscription or acceptance of
terms and conditions, contact the network service
provider.

connect to a Wi-Fi network
and the signal strength is
excellent but the software
does not update.
