I can probably help you but I need more info.
Lets start with the vehicle, What year ,? What specific model?, What type of head unit came out? Was it factory?
Did you use a wiring adapter, or just cut the plug off and hardwire it?. If so give me the color code of all the wires that you used in the dash. are their any left over but not hooked up? How many speakers? All Factory?
I don't need any info about the JVC Head unit.
Lets start with that, and we will take it from there.

Try this..Turn your radio off, take the fuse out (for the radio) for one minute. Replace it and turn the switch on. Turn the radio on and enter the code. If this dosnt work you may have the wrong code. If you enter the wrong code 3 times it may lock and you will have to wait an hour before entering again.

If the battery was recharged by someone who accidenly reversed the leads then it can kill a radio, usually blows radio fuse first tho. Im affraid the unit needs repair from what youre saying.

According to your requirement you have to purchase radio code or you can use car radio decoder software to decode your car radio. If you have experienced a dead battery, disconnected the factory radio harness or disconnected the battery to the vehicle then you must need radio code. Better to purchase a radio code. Before purchase determine of your radio type and do the following steps. The radio must be in LOC mode NOT in INOP mode. Turn the ignition ON. Press and hold presets buttons 2 & 3 or 1 & 4 for approximately 10 seconds. The radio display changes from LOC to a three-digit number. Write this number down. You will then have fifteen seconds max before the next step must be performed. Press the AM/FM button. The radio display changes to another three-digit number. Write this number to the right of the first one. You now have a six or four-digit number, the first three digits are from STEP 3 and the last three digits are from STEP 5. If you have a four digit number, it will show all four digits at the same time. Then purchase the code mentioning your car model and unlock the radio. You can purchase your code from radio-code.com by credit or debit card.
