A constant power source is essential in the retention of GPS data
inside VT-2200, and is required. Be sure to verify that the power
source you have chosen will work when the vehicle is not running, and
the keys are removed. Verify a 5-amp fuse is inline with the power and
ignition lead. This will protect the unit against power surges and
voiding the warranty.
Ignition
An ignition source is also required for proper installation of VT-
2200. Connect the white wire to the vehicle ignition source. This wire
can be found in close proximity to the main power wire. Be sure that
the tapped wire is a vehicle ignition wire and not an accessory wire.
Some vehicles have wires that are only powered when the vehicle is
running, this is the preferred wire. Ignition wires maintain a voltage
through the crank. Note: turn off all other vehicle accessories
including A/C, radio, etc. to ensure a good ignition source is found.
The best place to pull power is at the ignition harness leading to the
ignition switch.
If there are any questions on what wire colors to use, you can
contact Customer Support at 855.358.6178.
See Appendix A for specifications relating to power, ground and
ignition.
Late Model Vehicle Installation
When installing VT-2200 in any late model vehicle, verify
all connections using a digital multi-meter. In some
instances, obtaining power will require direct connection to
the battery. CAN-based vehicles will contain data lines that
will show voltage on the line itself (usually 5V), but the
line is actually a data line. Most late model vehicles can
utilize CAN-based ignition and accessory circuits so the
ignition line running down the center of the steering column
is actually a data circuit. Connecting VT-2200 to these
circuits can and will cause the unit to malfunction and may
damage the OEM electronic modules within the vehicle. As a
rule of thumb, always use the thickest wires as they carry
the most amperage. If there any questions, please contact
Customer Support at 855.358.6178.
