How to install and get the best use of in car navigation system?
An in-car GPS navigation system can be of two types in general:
- In-dash GPS navigation system
- Portable GPS navigation system
Using this short and effective guide, we try to provide you necessary tips, tricks and hacks to get the best out of an in-car navigation system, particularly the in-dash GPS system as they involve much greater expertise to operate. An in-dash GPS navigation system consists of a number of standalone parts, namely, car stereo with built-in screen, GPS antenna, and connection box for audio/video inputs and outputs. An in-dash navigation system requires much greater professional expertise to be installed as extra wiring connections are needed when compared to installing common in-dash stereos. While installing an in-dash GPS navigation system, the following points must be kept in mind:
Parking Brake Caution: While installing any equipment with a video screen in a car like the in-dash GPS navigation system, the video screen at the front should be compulsorily connected with the parking brake wire for safety. Many advanced navigation features in navigation systems remain disabled during the trip and one needs to stop his/her car to access them like looking up a contact in phonebook or changing the settings. Some in-dash systems also require connection with foot brake for greater safety.
Vehicle Speed Sensor (VSS): The vehicle speed sensor wire should be connected along with standard power and ground wires to the navigation system for accurate position and speed tracking. The vehicle speed sensor wire is used by cruise control to determine the current speed of a car and serves the same purpose for navigation system. By connecting the wire with the system, you make sure that the navigation system gets accurate hold of a vehicle’s moving ability and estimate the current position accurately. Just make sure that you do not connect the tachometer signal wire instead of VSS wire as the tachometer signal wire sends signal pulse for all the time during which engine is running, even if the car is standing still. The VSS wire instead only sends periodic pulses (800-1000 per mile) during the time when the vehicle is actually in motion.
Reverse Signal: A number of modern navigation systems also have a separate wire to connect to the car’s reverse signal wire to let the navigation system know if the car is moving backwards. If the system has this wire and you forget to connect it to the system, the accurate position and direction of a vehicle will not be tracked properly and the navigation system would fail in serving its purpose.
If you are apprehensive about your technical prowess to install an in-dash navigation system, you can always take help of a professional technical team which can easily help you in installing a GPS navigation system for your car. They also help you understand which wire should be connected to which one so that you do not fail in making accurate connections.
Tips to perfectly install GPS antenna of in-dash GPS navigation system
The in-dash GPS navigation system communicates with the global positioning system satellites using the GPS antenna that comes with the system. The antenna is waterproof and can be installed either inside or outside the vehicle. But in order to get accurate positioning and best results it is better to mount on the roof of a vehicle.
If you are looking to install the GPS antenna inside the car, you must keep in mind that the GPS antenna is not equipped to work through metal surfaces. Also, reception of signals gets prone to electromagnetic interferences when antenna is installed inside vehicle. You should never install the antenna on dashboard or rear deck of your car, if:
- You are using a wired rear windshield defroster
- Your car has a metallic window tint
- Your car is equipped with solar reflective windows
- You have mounted radio antenna to the windshield
Keep in mind that the antenna should be at least placed 5 inches away from any kind of physical obstruction, e.g. A pillar or 2-way communication antenna. Also, the GPS antenna is attached to metal sheet using any adhesive or magnet while the antenna cable is passed to the interiors of a car through the rear window sear or the door seal.
How to calibrate your GPS navigation system?
A GPS navigation system should be ideally calibrated according to the instructions provided by the manufacturer. Also, many systems are required to be calibrated after changing a car’s tire for best results.
A GPS navigation system is very easy to install and is similar to installing any in-dash receiver or amplifier. If you have previously installed any kind of in-dash receiver in your car, then installing an in-dash GPS navigation system will be surely a piece of cake for you.
Types of Navigation Systems
Remote-mount navigation systems
Remote-mount GPS navigation systems comprise of a dedicated navigation computer along with an external GPS antenna that is required to be connected to a compatible car stereo. A driver can interact with a remote-mount system in a similar way that is used for an in-dash system. Though obsolete, remote-mount systems are as effective as an in-dash system if the mapping data is updated and they are well-connected.
Portable GPS navigator systems
A portable GPS navigation system is easy to install and can be mounted using a suction-cup to the windshield or dashboard of a car. A 12-volt power adapter is used to power the portable GPS navigation system. To install a portable GPS navigator, clean up a small area that is not directly used to view the road (ideally the center of the windshield). Attach the suction-cup to the windshield and secure it to the glass. Many portable GPS navigators come with a different installation mechanism or apparatus like a bean bag mount. These mounts use a weighted non-slippery rubber pad to stay intact on an uneven surface. Some navigators also come with adhesive brackets for mounting directly to the dash. Keep in mind the above listed precautions for installing portable navigators with in-built GPS antennas for best performance and accurate positioning & navigation information.
