Based on your statement I can see three (3) possible problems:
1] Your CD player is not connected properly to your power supply or something is eating the voltage coming to your CD player. To fix this possible problem you have to check the connection of your CD player to the power supply, you must check if the voltage of your car's battery and compare it to the voltage coming to your CD player and be sure it is not bypassed by any other connection. To be sure there is no other connection bypassing your CD player, connect it directly to your car's battery or you may use an independent battery for the CD player.
To do this, connect the +wire of your CD player to the +terminal of your baterry, and then the -wire of your CD player to the-terminal of your car's battery.
2] Another possible problem that I can see is that there is an overload in your car's circuits. The possible solution is that you remove other component that is connected to your car's battery.
3] Another possible problem is that your car's battery is low in voltage already. The possible solution is to recharge your car's battery or buy a new one.
4] Another possible problem is that their is loose connection within the CD player that is triggered by the car's movement.The possible solution is to check the internal connections of your CD player. If something is loose you must connect it firmly.

I hope I solved your problem.

My radio cuts off and says call whenever i am driving

Hi Call on display means Call Service.

That means that a short or an incorrect voltage had been detected. The unit goes off to prevent further damage.

If this happens with vibration, or when turning on the ignition then it is usually a bad wiring at the back of the unit.

Do the cdx-4000x have a ipod plugin

No, not directly. Here is a link to Sony for your CDX-4000X Operating Instructions.
Belkin as well as many other companies make devices that plug into the ciggarette lighter and then into your iPod. There is an FM tuner controller than sends the music from the iPod to an FM station on your head unit. Belkin calls theirs a 'tunecast auto'. I believe it sells for about $30 USD.
