Sounds like you have a loose wire. check them all.

Take a torch and see if there are any foreign objects in the loading compartment. Children are know to insert for coins to just about anything they can squeeze through the ****.
Then try removing the system from the dash and open the top lid. see if you can clean the lens from a small cutout on the loading mechanism using a cotton ear bud. Do it in good light because the lens ( looks like a fish eye ) can oly been seen at an angle through the cutout.

The front control panel must be going out. Replace the front panel, or replace the entire head unit. Good luck!

Usually it's....

black = ground
red = switched battery power
yellow = constant batery power (for clock...etc)
orange = illumination
blue = amplifier turn on or accessory (electric antenna, amps etc)

green/white/purple/grey are speaker wires.

Hello headbanger42,

First I'd check all of the wiring and connections. Make sure that there's no bare wires, no cut or frayed insulation and no wires contacting metal on the vehicle or other wires.

If everything is connected properly and there's no shorts, press the reset button on the panel holder using a ball-point pen after detaching the control panel. (The clock setting and preset stations stored in memory will be .)

If that does not work, there's most likely an internal fault and the receiver needs service.

Hope this helps.

Retails for $206.90 easy to replace good luck..

For ten bucks, you can buy a new connector: http://www.jvcservice.com/store/ProductDetail.asp?part=JV16-0001A To figure out how to wire it: http://books.jvcservice.com/download/256614688/28879.pdf Page 25 describes the color of the wiring in the harness.

Same issue but pressing Power and SEL would not reset unit. Found solution. Once again disconnected the car battery. Removed the face unit from the radio base and then reconnected the battery. Replacing the face unit AFTER the power was re-established solved the issue. (Probably pulling the radio fuse rather than toying with the battery connection would have done the same thing.)
