To activate Siri, press and hold the “NEXT TRACK” button on the steering
wheel or car stereo. In addition, you can “press and hold” the button on the
lower left corner of the CarPlay screen to activate Siri if the factory screen
supports it. Ensure you install the microphone supplied with the VLite VT2
kit, unless the system uses a factory microphone, and that the Siri function
is enabled on your iPhone.
2. Phone Calls
You can make phone calls using CarPlay. You can start the phone call via the
CarPlay menu or Siri voice command. Make sure you connect your iPhone
to the VLite VT2 for phone calls. Check your iPhone’s Bluetooth settings if
you experience any difficulties. Unpair the iPhone from the factory
Bluetooth, as the calls will route to the CarPlay.
Ensure that you install the microphone that comes with the VLite VT2 unless
your VLite VT2 allows using a factory microphone. Refer to the Install Guide
for the microphone’s installation guidelines.

3. Other apps in Android Auto®
You can use any other apps supported by Android Auto® while using VLite
VT2. Note that you must install apps to your smartphone so they will
display on the VLite VT2 Android Auto® screen. Check the Android Auto®
support page to see what apps are compatible with Android Auto®.
3.4 Troubleshooting
If the Android Auto® does not connect, the below remedies are available:
1. Restart the smartphone.
2. Make sure your smartphone supports wireless Android Auto®.
Check the phone’s Settings and search for Android Auto®. If it does not
support wireless Android Auto, you will need to connect via USB instead.
3. Make sure you turn ON the Bluetooth on your smartphone and the
VLine VL2.
4. Go to Android Auto® Settings --> Connected cars and make sure the
option “Add new cars to Android Auto” is enabled on your phone.
5. If using a USB connection, try using a different USB cable. Make sure to
use high-quality USB Android® cables. If using a USB extension, try to
remove the USB extension cable and plug the “USB to Android” cable

necting it via USB to VLite VT2.

tion to car - only calls are on

7. If you are using a Samsung smartphone, you might need to set up the “routines”
for the wireless Android Auto to connect automatically. Check the article at https://
bit.ly/ samsung_routines to learn how to set up the routines for your Samsung
smartphone.
8. For wireless Android Auto® connectivity issues, reset the connection:
A. On your Android® phone:
1. Forget VLite2 from Bluetooth Settings
2. Reboot/Restart Android® Phone
B. On your VLite VT2:
1. Forget Android phone from Bluetooth Settings
2. Reboot/Restart VLite VT2 (Support -> All Settings -> About -> VLite System Updates
-> Reboot VLite)
9. If none of the above helps, clear the Android Auto® cache and storage.
To clear the data for Android Auto®, head to (Settings > Apps & notifications > See all
X apps > Android Auto > Storage & cache). Select “Clear Cache” first.
Clearing the cache only removes temporary files, so deleting the cache will not erase
any of your Android Auto preferences. If that did not help, clear the storage next.
Clearing the storage deletes all the data for the app, so you will likely need to config-
ure settings for Android Auto® again.
10. For USB connection issues, if your VLite VT2 stopped “seeing” Android Auto
connected, try to reboot/restart VLite VT2 (Support -> All Settings -> About -> VLite
System Updates -> Reboot VLite).

Under Android Auto® settings, locate the option “Activate Android UI.” Select the
option to activate Automatically (on connect). Tap to switch between Automatic and
Manual activation.
