After the things are ready, the first step to do is to disconnect the battery. This can be done by removing the negative end of the batter with the help of wrench or any other suitable tool. Then, an antenna jack that is present on HD radio is connected with the antenna of the car. This need not be done with the antenna input of the head unit but with the radio directly.
Next, take the black coloured wire from the lead set consisting of black as well as yellow wires. This black wire is then connected to the chassis of the car. A clean surface is chosen with no paint on it. There are some pieces that already come with wiring set. This can also be used. Then, yellow lead is connected to the twelve volt supply which is constant. This yellow lead had a fuse inline.
Then, the cable which is also known as IP BUS cable is connected with blue connector, to multi CD player if present. This cable is then connected to head unit. It is connected to blue connector which is found on this head unit. This connector on the radio is actually black in colour. A cable that is either blue or white comes out from head unit. This cable is connected to the auto antenna control terminal of the car. The manual of the car can be checked for this antenna. This is mainly for the control signal. Then, all the above wiring connections are secured by taping it with the electric insulation tape.
The radio is then mounted at a location that is convenient. They are provided with fasteners of the hook loop type. With the help of these fasteners, fix this unit with the carpet below the seat. Since the unit is operated and controlled from its head unit, the access to the radio is not very important. After the above connections are done the car battery is reconnected and the fixed radio is tested.
