How to Install an Aftermarket Navigation System in Your Car
An aftermarket navigation system adds value to your vehicle. The modern trend is to have this system built in to new vehicles. This is an especially important feature to anyone traveling in a new area. When you are buying a secondhand vehicle a navigation system is not always available and the task of installing one can fall on you.
Step 1 - Buy a System to Suit Your Needs
Choose a system according to your needs. There are many options available such as portable system and built in system. The following steps are to be followed for portable system.
Step 2 - Positioning
The positioning of the aftermarket navigation system is important as you do not want it obscuring your view of the preinstalled dashboard instruments or your view from the windshield. Preferably you will choose a position that’s level with the rest of your instruments. Airbag position is also a considerable factor when installing an aftermarket navigation system. The new installation should not impede airbag function in any way. The same applies to any vents for air conditioners or the like.
Step 3 - Installation
Most portable devices come with a strip of Velcro or a suction cup at the back for attaching the device to the dashboard. Either way they are simple to attach.
Step 5 - Connection
Some portable installations plug into the cigarette lighter while others run on batteries. When a lighter plug is available, you simply need to plug it into the lighter and it’s ready to go.
If you chose a Built-in System, then follow the below steps.

The first thing you need to do prior to installation is disconnect the battery. Then you can safely install the aftermarket navigation system.
Step 7 - Position the System
You need to install the unit in close proximity to your radio. It comes with a CPU and this requires that it be attached behind the Dashboard.

Once all the wires are connected to the stereo, you connect the CPU to the navigation system also according to the instruction manual.
Step 10 - Install the Antenna
The antenna is usually positioned somewhere on the dashboard against the windshield. You will attach it with screws and a screwdriver. It might be necessary for you to drill so be sure to not drill into anything other than the dashboard.
Step 11 - Attach the Cable
Carefully attach the cable from the antenna to the CPU making sure that it doesn’t obstruct any other dashboard functions.
Step 12 - Microphone
The microphone needs to be placed close to the CPU but check that it in no way hinders your driving.

Attach the aftermarket navigation system to the place where the stereo was housed and then put the dash board cover back in position.
Step 14 - Reconnect The Battery
Reconnect your battery and use the instruction manual as a guide to program the aftermarket navigation system.
