6.1 Installation steps and ways Check vehicle state before installation
a. Get key from owner and enter car to check appearance and all the systems including ignition,
sound, air-condition, door switch, trunk control or original alarm system. If there are some
problems, confirm with owner and fill the result in the access network form and after you get
signature from owner then start installation.
b. Get confirmation from owner whether owner has special requirement for device installation
position, whether original alarm system need to be removed. Record all these information. For top
grade car, if car system is so complicated that functional wires of this system cannot be installed,
you should explain clearly and get confirmation from owner.
c. If the car is a new one and no parts were taken apart before, if possible you should tell owner
which parts will be removed in case misunderstanding happens.
d. Get SIM card which should have call number display, voice call and GPRS internet functions from
owner for test.
e. Check if windshield has explosion-proof and heat insulation diaphragm which will affect receiving
of GPS signal and so that it can not get the longitude and latitude; if not, then hide GPS antenna
in dashboard and ensure there is no metal things above it; if it has this diaphragm, then you need
to hide the GPS antenna in front and at the back of bumper.
6.2 Installation points to remember
a. Important! Please read this entire installation guide before beginning the installation. The
installation of this GPS/GPRS system interfacing with many of the vehicle's system. Many new
vehicles use low-voltage or multiplexed systems that can be damaged by low resistance testing
devices, such as test lights and logic probes (computer safe test lights). Test all circuits with a high
quality digital multi-meter before making connections.
b. Don't disconnect the battery if the vehicle has an anti-theft-coded radio. If equipped with an air
bag, avoid disconnecting the battery if possible. Many airbag systems will display a diagnostic
code through their warning light after they lose power. Disconnecting the battery requires this
code to be erased, which can require a trip to the dealer.
c. Check with the customer on status LED location.
d. Remove dome light fuse. This prevents accidentally draining the battery. e. Roll down a window
to avoid being locked out of the car.
