How Install an In Dash GPS Navigation Unit
- Disconnect the main battery to prevent a short circuit problems whilst your fiddling around with your Vehicles electronics.
- Remove the trim from around the outside of your unit and the section that your unit will fit into.
- Remove the old unit from your dash board. This should be done carefully, not to bend the original panel. Use a flathead screwdriver and insert it into the gap and gently pry the unit out.
- Remove the screws from the existing unit and save these for later as you will need them again. Our advice is that you put these into some tape which will hold them steady for later.
- Disconnect any wires that are attached to your GPS Unit an re-attach these wires onto your new GPS unit making sure that you get the wires in the correct sockets. They should be clearly market, however you may need to refer to the instructions for the correct sockets.
- Insert the new GPS unit into the Dash and screw it in place using the same screws that you saved from earlier.
