Fuse installation for VRFM9 MP:3

Unit quit working and then realized that retainer ring holding fuse had come unscrewed. However, something appears to be missing as fuse is loose and falls out when I remove the unit from the cigarette lighter fixture. Is there some form of part that is supposed to hold the fuse intact inside the retainer ring? If so, where can I find a diagram of the specs and parts to identiy the piece I need and then order a replacement part?

Re: fuse installation for VRFM9 MP:3

there should be a spring to help hold the fuse in place,you might be able to get a replacement sring but you can get a new plug from a car place and then you can change the plug or you can take the plug apart and repair the you have..i know this will work as ive done this my self. please be careful when taking apart that you dont lose any thing in side the new plug..hope this helps.all the best..Lee Bruce.

On my pioneer, you have to shut the unit off, and hold down the source button. If that doesnt work, try holding down each button "one at a time"... Pioneers have run like that for years. You might find some extra equalizers too. Dont go changin too much.

When I plug the radar in the green dot turns on for a second then turns off, nothings on afterwards... I used a new wire and fuse and nothing....what could be wrong?

Does the unit work in another vehicle? If not, first thing to check is the fuse in the power cord. The adapter (part that plugs into the lighter socket) has a replaceable 2 amp 3 AG fuse inside it. The end of the adapter, which has the silver tip, unscrews to gain access to the fuse. CAREFUL: Unscrew slowly! The tip contains a spring which may fly out when disassembling. With use, screw cap on plug may loosen. Retighten occasionally.

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.

Yesterday I installed the Pioneer DEH-2050MPG in an old Beetle I just bought, and had the same problem. The instructions were completely useless; Ignore them.

Here's how to set the time...

1. Hold the source button down until clock starts flashing.
2. Use arrow buttons to set time.
3. Press source again to save.

That's what worked for me.

Clock Setting


press and hold the source button untill the unit powers off

then press the function button, untill the clock appears in the display
left or right switches between hours or min segments of the display, which will then blink, up and down changes the value.

to accept the changes press the source button.

I assume you dont have the user manual!? If you dont, check out my profile on here and you will get my email address, email me and I will send you a PDF of the manual.


Please remember to rate as a Fixya, if this works.
