20 Most Recent JVC KD-G801 CD Player Questions & Answers

Look for a pinhole button on the face, just left of the #1 radio preset. Use a ball point pen or paper clip to lightly hold this button for 2-3 seconds. You may do this with the key on. This will reset the radio's microprocessor. Let me know if this helps.

Which external jack plug? Please be a bit more specific

Please check if the wiring was done correctly. check the ground the all time +12 volt and the swittched +12 volt. If the set does not power up then I suggest that you MUST take the warrranty claim being a new set. Refer to the dealer before you can open the player so as not to void the warranty

you need to make sure 3 wire are connet the right way one is constant power,2 ground,3 acc. ingnition also there is 1 more wire you need to connect is the remote blue or blue/light blue.

need to check the yellow constant power wire on wire harness to see

1. connected to battery with constant 12 volts
2. if wire has power 12 volts

if no power check fuses to see if blown

with out this wire working right you will never have pre set station on radio or clock
with correct time

Yes... the wire designated for constant power which powers the clock and some of the lessor memory functions is disconnected.
I would remove the radio and look for the lead that is disconnected and have a constant power lead attached to it to cure this issue.
Have the mechanic who did it the first time do it.. as it was already paid for him to do so in the first place...

Hook your power wires and ground up to a cordless drill battery , 12 volt, or 14 volt. Or use jumper wires from car battery. Hit eject. You don't need all the speakers etc hooked up.

it's not for running your ipod or whatever else, it's for steering wheel control for those cars that have the feature. that's what it says in the manual anyway, there's gotta be a way to run the ipod through though for sure

well if there is alittle hole thing on the radio, you have to buy a wire addapter at walmart, then plug one end in the headphone hole and one end in the radio hole.

ebay or craigs list or do a search head unit parts

disconnecting the main harness will reset the microprosessor it is possible that it just locked up and resetting the unit by unplugging it may help. or you might have a bad switch in the face of your unit
if unplugging your jvc doesn't help you can e-mail me at [email protected]
