JVC drains battery when OFF, puzzling
The problem is actually the wiring. Check the installation manual, I guarantee the "pro" installer took a shortcut.There are two power wires (yellow & red +) and a ground wire (black -).Now, black goes to chassis grounding point. Easy.Yellow goes to a live terminal in the fuse block for constant 12V.This retains the settings and clock etc.Red goes to an ACCESSORY terminal in the fuse block (so key must be turned to at least ACC to allow it to be switched on).But in the case of my car, the idiot who installed it ran the red wire directly to the + battery terminal. That's wrong, and will drain the battery.Google for an installation manual, I'm certain your JVC head units will be the same procedure.
WHAT IS THE SRC BUTTON FOR ON A JVC RADIO
It simply means "source". These radios typically have AM/FM, CD, auxiliary (1/8" plug), USB, and some XM/Sirius input selections. The source button is how you choose.
I need wiring instructions
The user manual is available on jvc.com. Go to home page, click on support, then click on Instruction manual, then type the model number. Download it and save.
Most wiring now is standard colors....red=ignition(goes to a switched power source...Yellow=battery...goes to a hot all the time(even with key off)...black=ground...white=left front speaker positive...white w/blk stripe=left front speaker negative...gray=right front spkr +...gray/ blk=right front spkr - ...green=rear left +....green/blk rear left - ...violet=right rear +...violet/blk= right rear - ...light blue or blue with a stripe is the remote turn on lead either for an amplifier or power antenna...some radios have an orange/ with white stripe that connects to your parking light dimmer circuit to dim the radio light with the dash lights....and then you should have the antenna plug and possibly rca outputs that go to an external amp
HOW DO I HOOK UP
if there is an auxillary input on the radio you can plug it in through that, if not you need a fm transmitter to do it... you can pick em up at your local radioshack
Hold the sel button, then release. use the right arrow to scroll through the options until you get to clock h.
Use the volume knob to change the hour.
Press the right arrow again to get clock m
Use the volume knob to change the minute.
VAN AUTO HOOK UP KD-HDR1
This radio can not use a common ground. If your speakers are all grounded together you will blow up the amp IC in the radio. The negative speaker wires run at about 6 or 7 volts and so do the positive speaker wires.
Trust me, run new speaker wires, do not common ground any of these speakers

CD player heats up
The reason the CD it is gettng hot is because of the amplifier IC in the radio. The CD player is right in front of the amp IC and it is all in an enclosed area with little ventilation. They do get hot after a while.
It is not unusual for a CD to get hot after playing for a while.
The JVC stereos are known for having a bad spindle motor. That can cause the problem you are describing. A bad laser pick up can also cause the same thing.
There is no way of knowing just what the cause of your problem is without having it tested by a technician.
The laser pick up is more prone to failure from heat if it is getting weak.
The spindle motor is a little more common problem with the JVC car CD players.
But I have repaired both of those problems in JVC CD players many times.
I work at a JVC authorized service center, Most of the JVC CD players use the exact same CD mech, whether it is a cheap unit or a more exspensive one.
The only user action that you can do is to run a cleaning disc thru it for about 20 to 30 seconds. But that is not going to change your problem, you need to have it checked out at a service center, but if it is not under warranty it may not be worth getting fixed. The repair can run from $70 to $125 depending on the rates of the service center.
If you need any more help or questions answered, feel free to ask. And if this was helpful to you a good rating would really be appreciated.
