There're 2 ways to solve this problem: 1. Use car specific antenna adapters. Go to any local sound shop or even Best Buy and tell them your vehicles make/model. They should have one in stock or at least be able to order one for your specific vehicle. 2. It will not cost much to change TV antenna, no more than $20 to get double antennas. You can see Eonon's TV antenna here, it can be generally used for Analog TV in your car.

This is only used if your vehicle has a motorized antenna that pops up only when the radio is on, then retracts when the radio is off. A voltage is sent from the stereo through this wire to a relay which applied power to the antenna. If you don't need it the wire from the stereo should be capped off to prevent a short occurring if it were to ground out under the dash somehow.
make sure your antenna wire from car is hooked up. stereo will have no sound until it is.

your ground wire for the stereo is connected to the ignition wire of the car
Some headunits share a power antenna & remote wire are the same wire. If it is hooked up to power antenna and not hooked up to factory amp there is no signal to tell amp to power up
