Routing the GPS Antenna
The GPS Antenna module is magnetic as well as supplied with double sided
tape.
It can be mounted to the top of dashboard or to outside of vehicle whichever
you prefer. We recommend mounting it inside of vehicle on passenger side of
the dashboard as shown below. Make sure GPS antenna is facing up, and there
are no onstructions in front of it.
Plug VAUX cable into the CAMERA AV1 on VLine. Plug GPS (if unplugged)
into VAUX with the purple and green wires facing up. Note that there is
no GPS antenna for VLite (VLine Lite).

Routing the Microphone
Route microphone to a location where it will be able to pick up voice clearly.
We recommend to mount MIC nearby the rear view mirror but not directly
on windshield glass. Avoid sticking to the hard surface as it will pick up more
noise.
Plug the microphone into the MIC port of the VLine module

sure to reconnect all unplugged connectors back to the vehicle before
cycling the ignition.
Cycle the ignition and press AUX to enter VLine mode. You might need to press
AUX few times.
If VLine appears on the screen, and all factory functions such as climate
controls, reverse camera, AF/FM stereo, are working, you can mount the dash-
board back.

Mounting the VLine Module
Mount module in the location free of any moving parts. We strongly
recommend mounting the module in an easily accessible location such as
the glove compartment for an easy access to the USB ports and in case of
needing to upgrade firmware on the VLine module.

signal. There should be no any bends of the video cable next to the con-
nectors that go to the back of the stereo or VLine, and no any sharp bends
anywhere else.
Secure VLine with zip ties, velcro or mounting brackets to make sure the
VLine does not bounce or move while the vehicle is in motion.
Install the interface in a location free from heat, humidity, moving parts, or
direct sunlight. Beware of hot-air flow from your vehicle’s climate control
system.
