need a new unit cd rerader in unit have a problem

Detach the control panel. Check for a small hole with a reset button which can be only pushed with a carbon pen tip once to reset the unit. When the car is running keep this pressed for about 5 seconds. The unit will reset. Refer to the below web address manual page 3 for details & a diagram. https://www.manualslib.com/manual/449215/Jvc-Kd-R330.html?page=3#manual

Try the jvckenwood website. Or a quick foogle search should turn up numerous places to get it from

Constant power. In other words it should be hot even when the ignition is off. Most likely black. Put a voltage tester on the wire and to the ground point. If you read 12V with the ignition off, that's it.

What do you mean by a battery source? Have you tested that there is a live feed to the radio? Have you checked the fuses in the fuse box? Have you checked the fuse at the back of the radio?

Hi,

Do you have a Bluetooth adapter plugged into the KD-R330?

A compatible Bluetooth adapter (like the KS-BTA100) usually plugs into the rear auxiliary port of the receiver. It then needs to be "paired" with your Bluetooth device, for example, a Bluetooth phone headset.

What you're describing sounds like what can when no Bluetooth device has been "paired" yet.

If you don't HAVE a Bluetooth adapter connected to your KD-R330....is it possible you accidentally plugged something into its rear auxiliary jack? Or the front auxiliary? In other words, is it possible your KD-R330 receiver is mistaking some other device for a Bluetooth adapter?

Don't know if that helps at all...if there's no adapter issue, and nothing connected to the AUX jacks, probably your next step should be a call to JVC, or whatever number you were given for tech support.

On the bright side, since the receiver turns on, and responds to some commands, you probably didn't mess up anything major in the wiring. And, there's also the possibility the receiver is defective....certainly if this continues, and JVC can't help you, trying a replacement might be worth a try.

BTW, feel free to post a reply...I'm going to look further to see if there's any other documented issue besides an adapter that might cause the problem you're having.
