Question about Car Audio & Video

3 Answers

I have a PLCDCS90 Casette/cd head unit. My installation skills are pretty good. Usually never have any problems, but for some reason I'm not getting a connection. I can hear the speakers make a little sound when I hook everything up, and the unit warms up, but there is no visible display or functions. I’m using a Jeep/Eagle/Dodge Wire Harness receiver. triple checked all of the connections. Power supply is good. Fuses look good. Not sure what to check next

    I have a strong feeling there is something wrong with the unit (possibly the detachable face), Thanks for the confirmation.

    I've connected the new head unit using a brand new Jeep/Eagle/Dodge Wire Harness receiver, 1988-up, purchased from Crutchfield. All wires have been properly connected. Unit was properly grounded before connecting power supply. The head unit's harness is securely connected. Fuses are good. Again, can hear the connection through the speakers when initially plugged in but the unit will not turn on. (display will not light up and does not accept cd)

Hi chunter1989

Check if the plug that takes all the wires into the unit is connected properly.

But if you said that you checked this 3 times and found no fault , then this could also be a defective unit.

Also check what happens if you change the mode of the radio.

If all else fails , take it back to the retailer you bought it from and have them exchange it for a new unit.

You honestly shouldn't have to struggle with it.

Hope this is off help and good luck.

What type of cables are you using and what are the devices that you connected to your receivers?

    Let me know..

    check for this.

    1 Switch the ignition to the "ON" or "ACC" position.

    2. Replace the fuse with another 15A fuse.

    Do not use speakers of impedance less than 4 ohms; and allow the speaker
    wires to be shorted together when the unit is switched on.
    Otherwise it may overload or burn out the power amplifier stage.

Car stereo doesnt work when its hot outside. Sometimes the lights are on, sometimes not


Interesting. I've never met a temperature tempermental radio before. But before we decide that the radio has taken decision making skills that it will NOT work in heat, let's look at the wiring.

I would look at the constant and switched power connections on the unit. This may explain the lights problem. If the unit is aftermarket, did you install it using a wiring harness or is it hard wired. The reason I ask is if it was hardwired, maybe a wrong wire was connected. When it's hot outside, you usually run your air, right? Maybe there is a circuit problem there. Just a thought. Hope this helps.

When I put a casette tape into the tape player of my 2003 Hyundai Santa Fe double din cd tape head unit there is a message on the display that says TIGHT TAPE then the tape ejects how to correct this so...


If it does this with all of the tapes your cassette player needs to be cleaned. there might be some dust in there that is stopping it from working correctly. You can blow it out using an air compressor (NOT ON FULL) just blow it gently out so nothing gets moved from the air.

You can also use keyboard cleaner from any computer store (it is just a can of compressed air) walmart and zellers also have this for you.

If it only does it on that tape stick a pen through the round hold and wind it all the way around to the other side this should loosen the tape a bit for the player to play that tape.

Is the icbm-9711 is a good product


I've never used the products before, but the amps are usually pretty good. I would go with a different company though. I would go with Pioneer, Kenwood, or even Alpine. I know they're a little more expensive, but they've ALL been making head units longer. Several years ago Kenwood hit their 25th anniversary.

I installed a jvc kdr310 with a pioneer amp and single 12 in sub all worked well and as soon as i drove off less then a quarter of a mile down the road my head unit stopped functioning and said protect i...


the fact that the head unit cut out and went into protect implies that it probably has nothing to do with your pioneer amplifier. If i understood well the amplifier is running the sub woofer. If the speakers are running off the head unit check that there is no speaker cable touching metal causing a short. Sometimes while installing the speaker we don't realize that the speaker terminal can touch on the frame of the surface that it is secured to. If this surface is metal then you get a short, which then makes the head unit go into protect. There is also the possibility that a cable from behind the head unit has come lose or is bare in some place touching metal again. You see it is all usually about being shorted. Without knowing exactly how everything is installed, this is the best i can do. I hope this helps. dreamsystems

Have just purchased a cde-100 for an mx3. Does the "mounting sleeve" come with the unit? If so, is it attached to the unit as shipped? I am studying the installation instructions. Are there more explicit...


mounting sleeve is on the radio when you buy it in most of my experiences.

reinforcing the HEAD UNIT-(the cd player itself) with metal straps means that the DIN(the hole the radio goes into in your dash, either single or double) dash piece is probably made of a softer material, and you should mount a small metal strap, usually does not come with the unit, to the units mounting sleeve, and then mount it to the inside of the dashboard of the car with some screws or bolts. this will keep the cd player from moving around, bouncing, etc while you drive over bumps and such.

you could probably get some metal mounting straps either from the box the radio comes in (very few come with them) or get a dash install kit from an auto parts store or a walmart for your car that will probably include all of the things you need including the dash piece, any mounting hardware, and metal straps the factory recommends or deems necessary, and even a wiring harness adapter.

well, the USB problem i cant help you with, but if the cd isnt loading, theres probably something wrong with the loading mechanism, which usually means that the unit is faulty. it would be more cost efficient to buy a new head unit than to pay someone for the parts and labor to repair the one you have.
