hi lizzy, please make sure that the power wiring (red, black and yellow cables) of your unit is correctly connected to the vehicle. next check if the blk wire(ground) is connected to the chassis(metal body part) of your unit (use a mutimeter). if not then attach a wire from the body of your unit to the blk wire. also make sure that your antenna lead is connected to the unit, and that the antenna is securely grounded to the body of vehicle. once power is correctly connected your unit will light up a red LED light in the power/source button. if all this does not help it will be advisable to have unit checked at jvc service center. cheers!
This is because of a ground loop. Your radio is already grounded through your antenna. Unhook the radio ground wire (black wire) and tape it off. This will get rid of your engine static in the speakers.
If you have a female harness to connect to the veicle side you will pretty much color match. The only exception is that you may only have an amp turn on wire but only a power antenna on the vehicle. In this case you would connect blue w/white stripe wire from radio harness to the blue antenna wire on the vehicle side.
If you are doing a hardwire (factory plug has been cut off) you can obtain a wiring code for your vehicle at www.the12volt.com for most vehicles.
Make sure that you have the antenna plugged in and if you have a power antenna make sure that you hook up the solid blue antenna wire behind on the radio harness to the power antenna wire from the car plug.
